A ball weighing 10 gm hits a hard surface vertically with a speed of 5 m/s and rebounds with the same speed. The ball remains in contact with the surface for 0.01 sec. The average force exerted by the surface on the ball is:

Options:

Answer:

Solution:

Change in momentum is
$Δ p = 0.01 \times (5 - (- 5)) = 0.1 N s$ ; the average force is
$\frac{0.1}{0.01} = 10 N .$
