Question

A cheetah is running at 40 m/s and catches his prey at 12 m/s. The chase took 30s. What is the

acceleration?

Answer 1

Formula for acceleration:

`a=(Vf-Vi)/(t)`

acceleration(measured in m/s^2) = Final velocity(measured in m/s) - Initial velocity(measured in m/s) / time(measured in seconds)

__________________________________________________________

Given:

`Vi=40m/s`

`Vf=12m/s`

`t=30s`

`a=?`

__________________________________________________________

Finding acceleration:

`a=(Vf-Vi)/(t)`

`a=(12-40)/(30)`

__________________________________________________________

Answer:

`\fbox{a = -0.93 m/s squared}`
