Question

4. (15 pts) A small block with a mass 'm', is released from rest at an initial height 'h'. the mass slides down a ramp and then through a 'dip' with a given radius of curvature '. at the lowest point of the curve, the mass as a velocity of vc (velocity at curve). The mass continues back up and eventually slides over a friction patch of length 'd' when it eventually reaches an uncompressed spring. The mass compresses the spring and comes to a momentary rest. กา hu Find the initial height of the block, hi, when the mass is released from rest. Express your answer in the variables m, hi, Vc r, d, uk, k and g for local gravity a. Find the normal fore, 'N' acting on the block when it is at the highest point of the bump. Express your answer in terms of the variables m, hi, ve r, d, uk, k and g for local gravity. b. c. Find the distance the spring is compressed before it brings the block to rest. Express your answer in terms of the variables m, hi. ver, d, uk, k and g for local gravity.
