2. A rigid bar with mass m and length & slides down a vertical wall. Point B has horizontal velocity up and horizontal acceleration as with respect to the fixed OXY Z reference frame. (a) (5 points) What is the angular velocity was of the bar with respect to the fixed OXYZ . reference frame? Give the answer in terms of us, as, 6, 0, m, and g, as necessary. (b) (5 points) What is the angular acceleration WAS of the bar with respect to the fixed OXYZ reference frame? Give the answer in terms of us, as, 4, 0, m, and g, as necessary. FEMA D= my dip 7 Up, QB
