An elastic ball of mass `'m'` is suspended from a fixed point by an inextensible string. A small particle of same mass `m`, moving downwards at an angle of `37^(@)` with the vertical lits the ball directly with the velocity `v_(0)`. If the coefficient of restitution is `4//5`,
(`i`) find the velocity of the ball just after the impact.
(`ii`) determine the impulsive tension(i.e impulse) in the string at the instant of collision.

Explanation

To solve the problem step by step, we will analyze the collision between the two balls and apply the principles of conservation of momentum and the coefficient of restitution.

### Step 1: Analyze the Situation
We have two balls of mass `m`. One ball (let's call it Ball A) is stationary and suspended from a string, while the other ball (Ball B) is moving downward at an angle of `37°` with the vertical with an initial velocity `v_0`.

### Step 2: Resolve the Velocity of Ball B
The velocity of Ball B can be resolved into two components:
- Vertical component: \( v_{B_y} = v_0 \cos(37^\circ) \)
