During an impact test, the 2000-lb weight is released from rest when θ = 60°. It swings downwards and strikes the concrete blocks, rebounds and swings back up to θ = 15° before it momentarily stops. Determine the coefficient of restitution between the weight and the blocks. Also, find the impulse transferred between the weight and blocks during impact. Assume that the blocks do not move after impact.
