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; 1.Determine the force of tension of...
