A 2.00 kg block is placed at rest at the top of a 0.80 m long Q80 frictionless ramp that is inclined 0' at 25 relative to horizontal. The block slides to the right down the ramp onto a frictionless 1! horizontal surface, where it " *0 continues sliding an irrelevant distance until encountering an . ------------------------------------------------ ideal spring with spring constant :_ ______________________________________ ACE]! - _ _ - - - , - - - _ _ 160 me. The block compresses the spring by some displacement x before the block rebounds to the left. a} Find the maximum displacement x of the spring. b) Explain why the distance the block travels along the horizontal surface is irrelevant. Make sure your answer mentions energy and work. c] The block continues sliding to the left, across the horizontal surface, and then travels some distance d along the ramp before momentarily coming to rest (before sliding back down the ramp). Find d. d) Explain why d should or should not equal 0.80 m
