A body is thrown horizontally from the top of a tower and strikes the ground after three seconds at an angle of ` 45^(@)` ,with the horizontal . Then find ,
(i) The height of the tower

Explanation

To solve the problem, we will follow these steps:

### Step 1: Understand the problem
A body is thrown horizontally from the top of a tower and strikes the ground after 3 seconds at an angle of 45 degrees with the horizontal. We need to find the height of the tower.

### Step 2: Use the time of flight formula
The time of flight \( t \) for an object falling freely under gravity is given by the formula:
\[
