A ball is projected with velocity u 20 m s at an angle 60 to the horizontal towards a massive wall which approaches the ball with velocity u 7 m s After collision the ball retraces its path to the point of projection The coefficient of restitution between the ball and the wall is 3 10 k Find the value of k
