A rigid bar with mass m and length l slides down a vertical wall. Point B has horizontal velocity UB and horizontal acceleration ap with respect to the fixed OXYZ reference frame. (a) (5 points) What is the angular velocity wAB of the bar with respect to the fixed OXYZ reference frame? Give the answer in terms of up, ap, l, 0, m, and g, as necessary. (b) (5 points) What is the angular acceleration WAB of the bar with respect to the fixed OXYZ reference frame? Give the answer in terms of VB, QB, L, 0, m, and 9, as necessary.
