A particle is projected from the ground at an angle such that it just clears the top of a polar after `t_1` time its path. It takes further `t_2` time to reach the ground. What is the height of the pole ?

Explanation

To find the height of the pole that a particle just clears after being projected, we can follow these steps:

### Step 1: Understand the motion of the particle
The particle is projected from the ground at an angle and takes time \( t_1 \) to reach the top of the pole and then takes an additional time \( t_2 \) to reach the ground. The total time of flight is \( t_1 + t_2 \).

### Step 2: Use the total time of flight formula
The total time of flight for a projectile is given by the formula:
\[
