A sports car moving at 30m/s comes to a stop in 4.2s. What was the acceleration of the car?

I'm not great at Physics....but....I might be able to answer a few of these

 

 

 

Acceleration  =   Change  in Velocity /  Change in Time =   [ 30 - 0 ] / [ 0 - 4.2 ] =

 

[ 30m/s]  / [ - 4.2 s]  ≈   - 7.14 m/s^2
