A ball is thrown vertically upwards. It goes to a height 19.6 m and then comes back to the ground, Find the initial velocity of the ball .
Take g = 9.8 `m s^(-2)`

Explanation

To find the initial velocity of the ball thrown vertically upwards, we can use the equations of motion. Here’s a step-by-step solution:

### Step 1: Identify the known values
- Height (h) = 19.6 m
- Final velocity (v) at the maximum height = 0 m/s (the ball stops momentarily at the highest point)
- Acceleration due to gravity (g) = 9.8 m/s² (acting downwards)

### Step 2: Use the appropriate equation of motion
