Answer:
velocity = 16.67[m/s]
Explanation:
To solve this problem we must use the following expression of speed, where we see the relationship between displacement and time.
velocity = displacement/time [m/s]
displacement = 50 [m]
time = 3 [s]
velocity = 50/3
velocity = 16.67[m/s]

A Plane crashes into the side of a mountain. If the crash took place over 9
minutes and the planes velocity before the crash was 2000 yards per
second, what is the acceleration of the plane? *
Given parameters:
Duration of crash = 9min
Velocity before crash = 2000 yards per second
Unknown:
Acceleration of the plane = ?
Solution:
Acceleration is the change of velocity with time.
Acceleration = [tex]\frac{V - U}{t}[/tex]
where v is the final velocity
u is the initial velocity
t is the time taken
We need to convert the time into seconds from min;
60s = 1 min
So, 9min = 60 x 9 = 540s
So input the parameters and solve;
Acceleration = [tex]\frac{2000 - 0 }{540}[/tex] = 3.7yards/s²
The acceleration of the plane is 3.7yards/s²

Enlarged brain ventricles are presumed to signify __________. A. An excess of dopamine activity B. Frontal lobe abnormalities C. Development of brain tissue D. A deterioration of brain tissue.
Answer:
Enlarged brain ventricles are presumed to signify
____a deterioration of brain tissue____.
Explanation:
got it right
Enlarged brain ventricles are presumed to signify a deterioration of brain tissue. The correct option is D.
What is the deterioration of brain tissue?One or more of the ventricles swell as CSF builds up when an injury or sickness disrupts CSF circulation. Because the adult skull is stiff and cannot expand, the pressure inside the brain may significantly rise.
A chronic illness known as hydrocephalus causes fluid to accumulate in the ventricles deep inside the brain. It normally cannot be cured, but it can be controlled.
As a neurodegenerative disease that causes cognitive impairment and behavioral abnormalities, Alzheimer's disease is a progressive illness that impairs memory and other critical mental functions.
Therefore, the correct option is D. A deterioration of brain tissue.

How are distance and elapsed time different?
Answer:
hope it helps...
Explanation:
The length an object moves through its motion is called the distance. ... The motion of an object takes time to occur. That is, moving from one place to another happens in the course of time. Such a time interval is called the elapsed time.
PLEASE THANK MY ANSWER..
Distance is a numerical representation of the distance between two objects or locations. The elapsed time is the name given to such a period of time.
What is the distance?Distance is a numerical representation of the distance between two objects or locations.
The distance can refer to a physical length or an estimate based on other factors in physics or common use. |AB| is a symbol for the distance between two points A and B.
The relation between the distance and the time is found as;
distance = speed × time
[tex]\rm d = v \times t[/tex]
The distance is the length of time an item moves during its motion. An object's motion needs time to occur. That is, traveling from one location to another occurs across time.
The elapsed time is the name given to such a period of time. It is denoted by t.
Hence the denotation and the defination of both physical quantity is different.

What circumstances must be in place for there to be a lunar eclipse?.
Answer:
When the Sun, the Earth, and the Moon are all aligned in space, a lunar eclipse occurs. The Moon reflects the Sun's light onto the Earth. The Earth gets in the way of the Sun in this case, keeping sunlight from reaching the moon. A lunar eclipse happens if this alignment is ideal.

A hot air balloon hovers at 92.4 m above the ground. The pilot drops a box over the edge of the basket. How fast does the person standing 10 m away, have to go to catch the box, before it hits the ground?
Answer:
The person has to move at the speed of 2.30 m/s towards the dropping point to catch the box.
Explanation:
Let t be the time taken by the box to reach the ground and v be the speed of the person on the ground standing 10 m away from the dropping
point.
As distance=(speed) x (time), so
[tex]10=vt\cdots(i)[/tex]
Initially, the height of the box from the ground is 92.4 m.
So, the displacement, s, covered by the box when it reached the ground,
[tex]s=92.4[/tex] m in the downward direction.
The gravitational force action of the box is also in the downward direction.
The initial velocity of the balloon, u=0.
According to the equation of motion,
[tex]s=ut+\frac1 2 at^2[/tex]
where a is the acceleration, u is initial velocity and.
Here, [tex]a=g=9.81 m/s^2[/tex] (acceleration due to gravity) and s and a are having the same direction.
So, on putting the values in the equation, we have
[tex]92.4=0\timest+ \frac 1 2 (9.81)t^2[/tex]
[tex]\Rightarrow t^2=\frac{92.4\times 2}{9.81}[/tex]
[tex]\Rightarrow t=\sqrt{\frac{92.4\times 2}{9.81}}[/tex]
[tex]\Rightarrow t=4.34[/tex] seconds.
So, the time available for the man on the ground to catch the bot is 4.34 seconds.
Now, from equation (i),
[tex]10=v\times 4.34[/tex]
[tex]\Rightarrow v = 10/4.34[/tex]
[tex]\Rightarrow v = 2.30[/tex] m/s.
Hence, the person has to move at the speed of 2.30 m/s towards the dropping point to catch the box.

An airplane lands with an initial velocity of 70.0 m/s and then decelerates at 1.50 m/s2 for 40.0 s. What is its final velocity?
Answer:
10 m/s
Explanation:
vi = 70 m/s
a = -1.5 m/s²
t = 40 s
vf = vi + at
= 70 + (-1.5 x 40)
= 10 m/s
The final velocity will be "10 m/s".
Given:
Initial velocity,
[tex]v_i = 70 \ m/s[/tex]Deceleration,
[tex]a = -1.50 \ m/s^2[/tex]Time,
[tex]t = 40 \ s[/tex]As we know,
→ Final velocity, [tex]v_f = v_i+at[/tex]
By substituting the values, we get
[tex]= 70+(-1.5\times 40)[/tex]
[tex]= 70+(-60)[/tex]
[tex]= 70-60[/tex]
[tex]= 10 \ m/s[/tex]
Thus the above answer is appropriate.

The spot with the "maximum kinetic energy" should be on the lowest point of the roller coaster at the far left side on the bottom.Gravitational potential energy vs kinetic energyThe maximum gravitational potential energy is located at the highest peak which the roller coaster attains while as the roller coaster comes down from the peak the gravitational potential energy decreases while the kinetic energy increases.
The point at which the roller coaster should attain it maximum kinetic energy should be at the lowest point ( i.e far left side of the bottom ).
Hence we can conclude that error in the diagram is the spot with the "maximum kinetic energy" should be on the lowest point of the roller coaster at the far left side on the bottom.

A gun with a muzzle velocity of 65.2 m/s is fired horizontally from a tower. Neglecting air resistance, how far downrange in meters will the bullet be 2.7 seconds later
Answer:
s ≈ 35.8 m
Explanation:
Let's apply the uniform acceleration equation to find the vertical height travelled after 2.7 seconds.
[tex]s = ut + \frac{1}{2}at^2[/tex]
s = distance travelled
u = initial vertical velocity
t = time taken
a = gravitational acceleration
The gun is fired horizontally, hence there is no initial vertical velocity.
[tex]s = 0(2.7) + \frac{1}{2}(9.81)(2.7)^2[/tex]
[tex]s = 35.75745 m[/tex]
s ≈ 35.8 m

How does uniform motion relate to velocity and acceleration?
For an object to move in a uniform motion it has to have either a constant velocity or a constant acceleration. If the object has a constant velocity then it is moving at zero acceleration and this means moving with out slowing down or speeding up.
