A cyclist rides at a velocity if 12m/s.if the cyclist deceleates a rate of 1.5m/s.how long will take her to reach a velocity of 3m/s?
1)identify your variables -what is what ?
2)pick your equation
3)plug in and solve
Answer:
t=6s
Explanation:
v=3m/s
u=12m/s
a=-1.5ms-²
t=?
v=u+at
3=12+(-1.5)t
3-12=-1.5t
t=3-12/-1.5
t=6s
I am not sure if me is correct.
how is kinetic energy is stored
Answer:
Explanation:
Kinetic energy can be stored. For example, it takes work to lift a weight and place it on a shelf or to compress a spring. ... Kinetic energy can also be transferred from one body to another in a collision, which can be elastic or inelastic. One example of an elastic collision would be one billiard ball striking another.

A car accelerates from 1.5 to 18 m/sec in 9.6 seconds. Calculate its acceleration. and the other one is During a race, you speed up from 2.2 m/sec to 4 m/sec in 3.2 seconds. (a) What is your change in speed? ____ m/sec (b) What is your acceleration? ___ m/sec2
Answer:
(1) The acceleration is 1.72 m/s²
(2) (a) The change in speed is 1.8 m/s
(2) (b) The acceleration is 0.563 m/s²
Explanation:
(1)
Given;
initial velocity, u = 1.5 m/s
final velocity, v = 18 m/s
time of motion, t = 9.6 s
The acceleration is given by;
a = (v - u) / t
a = (18 - 1.5) / 9.6
a = 1.72 m/s²
(2)
Given;
initial speed, u = 2.2 m/s
final speed, v = 4 m/s
time of motion, t = 3.2 s
(a) The change in speed is given by;
Δv = v - u
Δv = 4 m/s - 2.2 m/s
Δv = 1.8 m/s
(b) the acceleration is given by;
a = Δv / t
a = 1.8 / 3.2
a = 0.563 m/s²

if an object is dropped 14 meters how long will it take for it to hit the ground
Hi! I believe your answer is 6.3 seconds because it takes 0.45 seconds for an object to fall 1 meter, so just multiply 0.45 by 14 and you'll get 6.3 seconds. I hope this helps you! Good luck and have a great day/night. ❤️✨

A jet airliner moving initially at 538 mph (with respect to the ground) to the east moves into a region where the wind is blowing at 937 mph in a direction 23 degrees north of east. What is the new speed of the aircraft with respect to the ground. Answer in units of mph
Answer:
The speed is "1447.576 mph".
Explanation:
The given values are:
Direction (north to east)
= 23°
Wind's speed
= 937 mph
Jet moving at a speed
= 538 mph
Now,
The velocity of jet airliner with respect to the ground will be:
⇒ [tex]v=v_{1}+v_{2}[/tex]
⇒ [tex]v=\sqrt{(538)^2+(987)^2+2(538)(937)\times Cos23^{\circ}}[/tex]
⇒ [tex]=1447.576 \ mph[/tex]

Which of the following is an accurate description of synaptic pruning?
Answer options:
A) Some connections are lost because critical stages of development were missed.
B) Some connections are lost so others can be strengthened.
C) Some connections are lost because of experimentation with drugs or alcohol.
D) Some connections are lost so that children become less dependent and are less tied to their parents.
Answer:
B) Some connections are lost so others can be strengthened.
Explanation:
Synaptic pruning refers to a natural process that occurs in the brain between childhood and adulthood. Extra synaptic connections are eliminated in order to increase the efficiency of neuronal communications. It is thought to be the brain’s way of removing connections that are no longer needed.

Answer:
Answer in explanation
Explanation:
What we want to do here is to basically put in words in the select pane that could actually beat complete the question.
The higher the distance between the effort and the function of a lever, the higher the force needed to complete the work.
The smaller the distance between the effort force and the fulcrum of a lever, the smaller the mechanical advantage , making the work easier
You are given a sample of metal and asked to determine its specific heat. You weight the sample and find that its weight is 28.4n.Ypu carefully add of heat heat energy to he sample and find that its temperature rises.Ehat is the samples specific heat?
Answer:
The samples specific heat is 14.8 J/kg.K
Explanation:
Given that,
Weight = 28.4 N
Suppose, heat energy [tex]E=1.25\times10^{4}\ J[/tex]
Temperature = 18°C
We need to calculate the samples specific heat
Using formula of specific heat
[tex]Q=mc\Delta T[/tex]
[tex]c=\dfrac{Q}{m\Delta T}[/tex]
Where, m = mass
c = specific heat
[tex]\Delta T[/tex] = temperature
Q = heat
Put the value into the formula
[tex]c=\dfrac{1.25\times10^{4}}{\dfrac{28.4}{9.8}\times(18+273)}[/tex]
[tex]c=14.8\ J/kg. K[/tex]
Hence, The samples specific heat is 14.8 J/kg.K

Courts often depend upon recovered memories is the wrong statement about the hypnotic regression.
What is hypnotic regression?Hypnotic regression is a contentious method because it can have a number of negative effects on the subjects who undergo it. For the beginners, the memories recovered through any regression can be doubtful and not trust-worthy. All the suggestions or leading questions from the hypnotist or other people of witnesses can affect the memory.
The previous lives memories will be found by the hypnotic technique as a past life regression. If they used to remember the past life by this method they have high chance of getting into the traumas.
Regression therapy mostly used to identify the cause of your current thoughts and reactions. Therapists who is using this techniques to access subconscious memories that are guiding your current behaviour.

Theo will recall which of our sensory systems can also send information to the brain through the spinal nerves? Select one: a. Taste b. Vision c. Hearing d. Touch
Answer:
Touch ( D )
Explanation:
The sense of touch can send information to the brain via the spinal cord and also in some cases the information sent by the sense of touch can as well be processed via the spinal cord
The Touch sensory system is made up of sense receptors which carry the information to be sent to the Central nervous system which the brain and the spinal cord is an essential part
