Question

A 0.13 kg ball is moving at 6.6 m/s when it is hit by a bat, causing it to reverse direction and having a speed of 10.3 m/s, What is the change in the magnitude of the momentum of the ball

Answer 1

Answer:

Change in momentum = 2.197 kgm/s

Explanation:

Momentum = MV

Initial momentum = MU

Final momentum = MV

Computation:

⇒ Change in momentum = MV - MU

⇒ Change in momentum = M (V - U)

⇒ Change in momentum = 0.13(-10.3 - 6.6)

⇒ Change in momentum = 0.13(16.9)

⇒ Change in momentum = 2.197 kgm/s
