m = mass of the object
h = height from which the ball is dropped = 50 m
d = distance during which the force due to sand act on the ball = 5 cm = 0.05 m
g = acceleration due to gravity = 9.8 m/s²
F = force acting on the ball due to sand
Using conservation of energy
work done by the force due to sand on the ball = potential energy lost by the ball
F d = mgh
F (0.05) = m (9.8) (50)
F = 9800 m
