Question

I will give all my points For who ever answers this

A ball rolls down a ramp. starting from rest. After 4.9 seconds, its velocity is
7 m/s. What is the acceleration of the ball?

Answer 1

1.43 m/s/s

Step-by-step explanation:

`a= (vf-vi)/(t)`

vi=0m/s

Vf=7m/s

t=4.9

`7/4.9=1.4285714285714284`

or 1.43 m/s/s
