A ball is tied to a string and swung in a horizontal circle with a tangential speed of 2.5 m/s. The length of the string is 1.5m. Calculate the ball’s centripetal acceleration.

Answers

Answer 1

Answer:

[tex]a_c=4.17\ m/s^2[/tex]

Step-by-step explanation:

Centripetal Acceleration

It's the acceleration of an object moving in a uniform circular motion that pushed the object toward the center.

Its magnitude can be calculated as follows:

[tex]\displaystyle a_c=\frac{v^2}{r}[/tex]

Where:

v = tangential speed

r  = radius of the circle

The ball is tied to a string describing a circular motion with a radius of r=1.5 m. The tangential speed is v=2.5 m/s, thus the acceleration is:

[tex]\displaystyle a_c=\frac{2.5^2}{1.5}[/tex]

[tex]\displaystyle a_c=\frac{6.25}{1.5}[/tex]

[tex]\mathbf{a_c=4.17\ m/s^2}[/tex]

Answer:

64

Step-by-step explanation:

If you do the work:

1) Start with the whole numbers

20 x 3 = 60

2) Move to multiplying fractions

20 x 1/5

2a) To do this, start by turning the whole number into a fraction

20 x 1

1       5

2b) Cross-multply

20 x 1 = 20

1    x 5 = 5

2c) Divide

20/5 = 4

3) Add products

60 + 4 = 64

Answers

Answer:

I=12

Step-by-step explanation:

y=108

I=108/9

Answer:

y = 12l

Step-by-step explanation:

This is the proportional relationship

Let the equation be:

y = rl, where y- money earned, l- number of hours, r- hourly rate

We have:

108 = 9rr = 108/9r = 12

The required equation is:
