PIn the figure, a solid 0.2 kg ball with radius 0.4 m rolls 1. smoothly along a horizontal frictionless plank with linear velocity of 4 m/s before elastically colliding with another solid ball of mass 0.1 kg standing at rest on the top of the ramp at height H = 7 m. After the collision 0.1 kg ball rolls smoothly down the ramp until it reaches the horizontal section at the end of the track, at height h = 2 m, and flies off the ramp. What will be the velocity of the second ball just before it flies off the ramp?
