A 5 lb. pendulum (1) is released from rest when the angle is 0
̊. A 2-lb crate (2) is at originally at rest on a rough surface µ =
0.2. The pendulum strikes the crate at an angle 90 ̊ with a
coefficient of restitution of 0.8. The crate slides on a
frictionless curve surface until it became to rest by a linear
spring (D). If the cord has L= 2.25 ft long;

A uniform slender bar of mass M = 3.2 kg and length L = 1.78 m is translating on the smooth horizontal x-y plane with a velocity vm= 1.80 m/s when a particle of mass m = 0.36 kg traveling with a velocity Vm=5.52 m/s as shown strikes and becomes embedded in the bar. Determine the final linear velocity of the center of mass of the system and the angular velocity of the bar with its embedded particle. 3L 4...

(a) A uniform bar BC with one end, B, on the ground has a mass of 15 kg and falls from rest when 0 90°. It strikes the edge at A when 0-60°. If the bar then begins to pivot about this point after contact, determine the bar's angular velocity just after the impact. Assume the bar does not slip at B as it falls until it strikes A. The moment of inertia of the uniform bar about its mass...
