A body is thrown with a kinetic energy of 5 j. What will be its kinetic energy at the highest point of its motion if the horizontal range is maximum ?

Explanation

To solve the problem step by step, we will follow the principles of projectile motion and kinetic energy.

### Step 1: Understand the Initial Conditions
The body is thrown with an initial kinetic energy (KE_initial) of 5 Joules.

### Step 2: Relate Kinetic Energy to Initial Velocity
The formula for kinetic energy is given by:
\[ KE = \frac{1}{2} m u^2 \]
