Question

If Bob, a baseball player, is swinging a bat that has a mass of 5 kg, with a velocity of 15 m/s. When he hits the ball that has a mass of 2.5 kg, what will the velocity of the ball be?

Answer 1

Answer:

30 m/s

Explanation:

Using law of comservation of momentum

m1v1 = m2v2

5 x 15 = 2.5 x v2

So, v2= 5 x 15 / 2.5

v2 = 30 m/s
