Question 225: Centre of Mass and Rotational Motion

Question

A player caught a cricket ball of mass $$150$$ $$g$$ moving at a rate of $$20$$ $$m/s.$$  If the catching process is completed in $$0.1s,$$ the force of the blow exerted by the ball on the hand of the player is equal to

Accepted Answer

We know, Force$$ 	imes $$ time = Impulse = Change in momentum
$$	herefore$$ $$F 	imes t = m\left( {v - u} ight)$$
$$ \Rightarrow $$ $$F = {{m\left( {v - u} ight)} \over t} = {{0.15\left( {0 - 20} ight)} \over {0.1}} = 30N$$

Answer

$$150$$ $$N$$

Answer

$$3$$ $$N$$

Answer

$$30$$ $$N$$

Answer

$$300$$ $$N$$

Centre of Mass and Rotational Motion

A player caught a cricket ball of mass $150 g moving at a rate of 20 m/s. If the catching process is completed in 0.1s,$ the force of the blow exerted by the ball on the hand of the player is equal to
