A stone is thrown horizontally from the top of a cliff and strikes the ground after 5 seconds, at an angle of `45^(@)` with the horizontal . Calculate
(i) height of the cliff.
(ii) speed of projection of the stone .

Text Solution

AI Generated Solution

To solve the problem step by step, we will break it down into two parts: calculating the height of the cliff and the speed of projection of the stone. ### Step 1: Calculate the Height of the Cliff 1. **Understanding the motion**: The stone is thrown horizontally, which means its initial vertical velocity is 0. The only force acting on it in the vertical direction is gravity. 2. **Using the formula for vertical motion**: The height \( h \) of the cliff can be calculated using the formula for distance under constant acceleration: \[ ...
