Auniform square crate is released from rest with corner d directly above a and it rotates about a until its corner b impacts the floor and then it rotates about b. the floor is rough enough to prevent slipping and the corner at b does not rebound on impact. determine, (a) as a function of g and `, the angular velocity of the crate ! e2 just before impact. (b) as a function of ! e2, the angular velocity of the crate immediately after impact ! e3. (c) the fraction of energy lost during the impact. (d) the maximum achieved after the impact. during the impact, assume that the weight force is non-impulsive.
