A particle is projected at an angle `theta` from the horizontal with kinetic energy (T). What is the kinetic energy of the particle at the highest point ?

Explanation

To find the kinetic energy of a particle at the highest point of its trajectory when projected at an angle \( \theta \) with an initial kinetic energy \( T \), we can follow these steps:

### Step 1: Understand the Components of Velocity
When a particle is projected at an angle \( \theta \), its initial velocity \( u \) can be resolved into two components:
- Horizontal component: \( u_x = u \cos \theta \)
- Vertical component: \( u_y = u \sin \theta \)

### Step 2: Analyze the Motion at the Highest Point
