The equation of motion of a body are given such that horizontal displacement x = 3t meter and vertical displacement , `y = 4t- 5t^(2)` meter , where "t" is in seconds. Find the angle of projection , velcoity of projection and horizontal range?

Explanation

To solve the problem, we will follow these steps:

### Step 1: Identify the equations of motion
We are given the horizontal and vertical displacement equations:
- Horizontal displacement: \( x = 3t \) meters
- Vertical displacement: \( y = 4t - 5t^2 \) meters

### Step 2: Compare with standard equations
