100 g of an iron ball having velocity 10 ms⁻¹ collides with a wall at an angle 30° (measured from the wall) and rebounds with the same angle. If the period of contact between the ball and the wall is 0.1 s, then the average force experienced by the wall is

Answer: (A)

Solution

Only the velocity component perpendicular to the wall reverses. That component is v
