A stone is dropped from the top of a tower of height 100 m. The stone penetrates in the sand on the ground through a distance of 2m. Calculate the retardation of the stone.

Text Solution

AI Generated Solution

To solve the problem step by step, we can break it down into two parts: the motion of the stone as it falls from the tower and the motion of the stone as it penetrates the sand. ### Step 1: Calculate the final velocity of the stone just before it hits the ground. 1. **Identify the known values:** - Height of the tower (h) = 100 m - Initial velocity (u) = 0 m/s (since the stone is dropped) - Acceleration due to gravity (g) = 10 m/s² ...
