A ball of mass 0.1 kg is thrown vertically upwards with a speed of `7 ms^(-1)` . Calculte the kinetic and potential ebergies after half second .

Explanation

To solve the problem step by step, we will calculate the kinetic energy and potential energy of the ball after half a second of being thrown upwards.

### Step 1: Given Data
- Mass of the ball, \( m = 0.1 \, \text{kg} \)
- Initial speed, \( u = 7 \, \text{m/s} \)
- Acceleration due to gravity, \( g = 9.8 \, \text{m/s}^2 \) (acting downwards)
- Time, \( t = 0.5 \, \text{s} \)
