A 1.5-Ib sphered A is released from rest when theta_A = 45degree and strikes a 3-lb sphere B which is at rest. Knowing that the coefficient of restitution is e = 0.75, determine the values of theta_A and theta_B corresponding to the highest positions to which the spheres will rise after impact.
Block A, having a mass m, is released from rest falls a distance h and strikes the plate B having a mass 2m. If the coefficient of restitution between A and B is e, determine the velocity of the plate just after collision. The spring has a stiffness k.
1. (30 points) A 2-kg block A is pushed up against a spring compressing it a distance r-0.1 m (i.e., the spring is unattached to the block). The block is then released from rest and slides down the 20° incline u it strikes a 1-kg sphere B that is suspended from a 1-m inextensible rope. The spring constant 800 N/m, the coefficient of friction between A and the ground i length of the spring d-1.5, and the coefficient of restitution...
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...
