Question

A man throws a ball of mass 150g to a wall with a velocity 20m/s and its rebounce with same velocity. Find the change in momentum in this process.
​

Answer 1

Answer:

4800 N

Explanation:

4800 N

Impulse=F×t= Change in Momentum

⇒ Change in Momentum =mv−mu=0.15(12)−0.15(−20)=4.8

⇒F×0.001=4.8 

⇒F=4800N 

Therefore 4800 N
