Elastic ball , Inextensible string

    Elastic ball , Inextensible string !!!!!!!!!

    An elastic ball of mass 'm' is suspended from a fixed point by an inextenible string. A small particle of same mass 'm' moving downwards at an angle of 37 degrees with the vertical hits the ball directly with the velocity 'v'. If the coefficient of restitution is 4/5.

    a)Find the velocity of the ball just after the impact.
    b)Determine the impulsive tension (impulse) in the string at the instant of collision.

    Think of the equation of elastic collision. Which law is applied?
