A block of mass m [kg] slides from rest a distance d [m] down a frictionless incline at angle theta where it runs into a spring of spring constant k [N/m]. When the block momentarily stops, it has compressed the spring by x [cm]. What is: (a) Distance d: (b) The distance between the point of the first block-spring contact and the point where the block's speed is the greatest? (c) The velocity of the block? Can you symbolically show me how to prove each part a, b, and c?
