Question

A ball of mass $0.5 k g$ moving with a velocity of $2 m / s$ strikes a wall normally and bounces back with the same speed. If the time of contact between the ball and the wall is $1$ $millisecond$ , the average force $in N$ exerted by the wall on the ball is

Open in App

Solution

$Δ p = 2 m v$

$F = \frac{Δ p}{Δ t}$

$= \frac{2 m v}{Δ t}$

$\frac{2 \times 0.5 \times 2}{10^{- 3}}$

$= 2000 N$

Final answer: $2000 N$
