Question

Block A (M = 10 kg) is released from rest and slides down an initially frictionless ramp (θ= 30°, L = 10 m). It then passes over a rough patch of ground (µk= 0.633 and d = 5m) before impacting block B. Block B (m = 20 kg) is initially at rest and suspended by a rigid bar of negligible mass and length R = 5m. The coefficient of restitution during the impact is e = 0.75. Determine the maximum deflection angle reached by Block B after impact.

    As shown below (not to scale), a block of mass starts from rest and slides down a frictionless ramp of height h. Upon reaching the bottom of the ramp, it continues to slide across a flat frictionless surface. It then crosses a "rough patch" on the surface of length d=10m. This rough patch has a coefficient of kinetic friction uK=.1. After crossing the rough patch, the block's final speed is vf=2m/s. What is the height of the ramp? Hint: I...
