A small metallic spherical ball is dropped from height h on the wet clay on the Earth surface. It travels distance S inside the wet clay before it stops. The uniform resistive force offered by the clay to the ball, as it penetrates a vertical distance S through the clay, is (the size of the ball is ignored as compared to S)

A

$$mg\left(1 + \frac{S}{h}\right)$$

B

$$mg$$

C

$$mg\left(1 + \frac{h}{S}\right)$$

D

$$mg\left(1 + \frac{h}{S}\right)^2$$
