A particle is dropped from the top of a tower. It covers 40 m in last 2s. Find the height of the tower.

Explanation

To solve the problem of finding the height of the tower from which a particle is dropped, we can follow these steps:

### Step 1: Understand the problem
We know that a particle is dropped from the top of a tower and it covers 40 meters in the last 2 seconds before it hits the ground. We need to find the total height of the tower.

### Step 2: Use the equations of motion
Since the particle is dropped, its initial velocity (u) is 0. The distance covered by the particle in time t can be given by the equation:
\[
