A ball thrown with velocity 30 m/s and making an anlge 37° with horizontal. The ball strikes a vertical wall at a distance of 12 m from the point of projection and coefficient of restitution between wall and the ball is equal to 0.5. What is the velocity of the ball just after impact on the wall ?
- 17.7 m/s
- 15.6 m/s
- 20.4 m/s
- 19.4 m/s
Answer
(D) 19.4 m/s
