Problem 1: Sphere A with mass 2 kg is dropped from rest h = 4 m above the smooth ramp- shaped block (mg = 10 kg). The block is initially at rest on a smooth horizontal surface. If the coefficient of restitution for the impact is e = 0.8, find how far the block has moved 3 seconds after the impact. Neglect the size of the sphere and assume the block remains in constant contact with the supporting surface. h 9 B 309 Figure 1: Problem 1
