A ball thrown up is caught by the thrower after ` 4 second`. How high did it go and with what velocity was it thrown ? How far below its highest point was in ` 3 second ` after starts ? Acceleration due to gravity is ` 9.8 ms^(-2)`.

Explanation

To solve the problem step by step, we will break it down into three main parts:

1. **Finding the initial velocity (u) with which the ball was thrown.**
2. **Calculating the maximum height (h) reached by the ball.**
3. **Determining how far below its highest point the ball was at 3 seconds after it was thrown.**

### Step 1: Finding the Initial Velocity (u)
