A light ball falling on ground, after striking the ground rises upwards. Explain the reason.

Text Solution

AI Generated Solution

### Step-by-Step Solution: 1. **Understanding the Scenario**: - A light ball is dropped from a height and falls towards the ground due to the force of gravity acting on it. 2. **Impact with the Ground**: - When the ball strikes the ground, it exerts a force (let's call it F) on the ground due to its weight and the speed it has gained while falling. ...

A steel ball is dropped from th roof of a building. A man standing in front of a 1-m high window in the building notes tha the ball takes 0.1 s to the fall from the top to the boottom of the window. The ball continues to fall and strikes the ground. On striking the ground, the ball gers rebounded with the same speed with which it hits the ground. If the ball reappears at the bottom of the window 2 s after passing the bottom of the window on the way down, dind the height of the building.

Joe throws a ball upwards from a certain height above the ground level. The height of the ball above the ground after time t seconds from when the ball was thrown is given by the expression h(t)= -(t-a)^(2)+b .
