2. A uniform slender rod of mass m and length / strikes the ground against the stop with a mass center velocity vai but with zero angular velocity. Immediately before the impact, the velocity vy has an angle o with respect to the rod, and the rod has an angle of @ with respect to the horizonal direction. Assuming no rebound during impact, and the rod rotates about A after impact without friction, find: (a) The absolute angular velocity (8) of the rod immediately after impact (10 pts). (b) The absolute velocity of the center of the rod immediately after impact (vez) (5 pts). () The absolute an (d) The gular acceleration of the rod immediately after impact (8) (5 pts). absolute acceleration of the center of the rod immediately after impact (agz2) (5 pts). () The minimum initial velocity ve; for which the rod will rotate about A to the vertical position (15 pts). ' (f) The reaction force by the stop to the rod immediately after impact (10 pts). %
