Question

A cat rolls up a hill. It’s initial Velocity is 10 m/s.n It’s final velocity is 0 m/s. The time was five seconds. Calculate Acceleration

Answer 1

`\boxed {\boxed {\sf a= -2 \ m/s^2}}`

Step-by-step explanation:

Acceleration can be found by dividing the change in velocity by the time.

`a=(v_f-v_i)/(t)`

The final velocity of the cat was 0 meters per second and the initial velocity was 10 meters per second. The time was 5 seconds.

`v_f=0 \ m/s\\v_i=10 \ m/s\\t= 5 \ s`

Substitute the values into the formula.

`a=(0 \ m/s-10 \ m/s)/(5 \ s)`

Solve the numerator.

• 0 m/s-10 m/s= -10 m/s

`a=(-10 \ m/s)/(5 \ s)`

Divide.

`a= -2 \ m/s^2`

The acceleration of the cat was -2 m/s². The negative acceleration indicates slowing down or stopping.
