Vedclass · Answer

(A) The impact of a moving object depends on its momentum,which is the product of its mass $(m)$ and velocity $(v)$,given by $p = m 	imes v$.$1$. $A$ table tennis ball has a very small mass,so even at high speeds,its momentum is relatively low,causing negligible impact.$2$. $A$ cricket ball has a significantly larger mass compared to a table tennis ball. When it moves at a high velocity,its momentum $(p = mv)$ becomes very high.$3$. According to Newton's second law,the force exerted during an impact is proportional to the rate of change of momentum. Since the cricket ball carries much higher momentum,it exerts a larger force upon impact,which can cause injury.

During a game of table tennis,if the ball hits a player,it does not hurt him. On the other hand,when a fast-moving cricket ball hits a spectator,it may hurt him. State the reason.
