A baseball is hit with a bat. The direction of the ball is completely reversed and its speed is doubled. If the actual contact with the bat lasts 0.41 s, what is the ratio of the acceleration to the original velocity?

Respuesta :

The solution would be like this for this specific problem:

 

Given: velocity = -2v

So:

Δv = v - (-2v) = 3v

a = Δv / Δt

= 3v / 0.41

= 7.32

 

So, the ratio of acceleration of the baseball to its original velocity is 7.32
