The cricket ball has more mass and velocity.

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.

Body	Mass $(kg)$	Speed $(m s^{-1})$
$A$	$1$	$10$
$B$	$2$	$9$

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.

In the following table,the mass and speed of two bodies are given. Which body has more momentum? Justify your answer.
Body Mass $(kg)$ Speed $(m s^{-1})$
$A$ $1$ $10$
$B$ $2$ $9$

$A$ certain force exerted for $1.2 \, s$ raises the speed of an object from $1.8 \, m s^{-1}$ to $4.2 \, m s^{-1}$. Later, the same force is applied for $2 \, s$. How much does the speed change in $2 \, s$?
