A ball is projected from ground with a speed `70m//s` at an angle `45^(@)` with the vertical so that it strikes a vertical wall at horizontal distance `(490)/(3)m` from the point of projection. If the ball returns back to the poin tof projection without any collision with ground then find the coefficient of restitution between the ball and wall.
