A 2 kg block is initially at rest on top of a frictionless at an angle of 60 degrees with respect to the horizontal and is sitting on top of a table. The surface of the table is also frictionless and it is 1 meter above the floor. ramp. The ramp is inclined The block is released and it slides 4 meters down the ramp, across the table and flies off the table onto the floor. A) Find the speed of the block when it flies off the table.

Based on your measurements of vertical position vs time you should have noticed that the maximum height of the ball decreases with each subsequent bounce. A basic analysis of kinetic energy and gravitational potential energy conservation would imply that each bounce should result in the ball returning to the same height from which it was initially dropped. Explain why the height of each subsequence bounce decreases, and why this does not violate the overall conservation of energy.
