A stone is projected at angle of `tan^(-1)(3//4)` to the horizontal with a speed of `30ms^(-1)`. Find its position after 2 seconds. `g = 10ms^(-1)` ?

Explanation

To solve the problem step by step, we will break down the motion of the stone into its horizontal and vertical components.

### Step 1: Determine the angle of projection
The angle of projection θ is given as:
\[ \theta = \tan^{-1}\left(\frac{3}{4}\right) \]
From this, we can find the sine and cosine of the angle:
