Question

A cricket ball of mass 500 gram is moving with a speed of 36 km/hr. If it is reflected back with the same speed
what will be in the change in momentum.​

Answer 1

Explanation:

Initial velocity of the ball   u=−36 km/h=−36×185=−10 m/s

Initial momentum   Pi=mu=−0.5×10=−5 kg m/s

Final velocity of the ball   v=36 km/h=36×185=10 m/s

Initial momentum   Pf=mv=0.5×10=5 kg m/s

Impulse on the ball   I=Pf−Pi=5−(−5)=10 kg m/s

Answer 2

Answer:

The answer iswhat will be in the change in momentum will be

10 kg ms 1
