: Problem 1 The Ball Strikes The Smooth Wall With A Velocity Of 20 M S As Shown And Rebounds At An Angle With A Velocity 1 (93.83 KiB) Viewed 23 times

Problem 1: The ball strikes the smooth wall with a velocity of 20 m/s as shown, and rebounds at an angle with a velocity (vb)2. If the coefficient of restitution between the ball and the wall is e = 0.85, determine the velocity of the ball just after impact. (b)2 8 30° (um) = 20 m/s
