A particle of mass m is strikes on ground at an angle of incidence `30^(@)` with initial speed of 5 m/s . Calculate (i) its velocity after impact (ii) angle of reflection . Given that the coefficient of restitution is `1/(sqrt(3))`

Explanation

To solve the problem step by step, we will break down the calculations for both parts of the question: (i) the velocity after impact and (ii) the angle of reflection.

### Step 1: Resolve the initial velocity into components
The initial velocity \( V \) of the particle is given as 5 m/s, and it strikes the ground at an angle of incidence of \( 30^\circ \).

- The horizontal component of the velocity \( V_x \) can be calculated using:
\[
V_x = V \cdot \cos(30^\circ) = 5 \cdot \frac{\sqrt{3}}{2} = \frac{5\sqrt{3}}{2} \text{ m/s}
