1. The angular position of a rod varies at 20.0? radians from time t = 0. The rod has two beads, as shown in the following figure: one 10 cm from the axis of rotation and the other 20 cm from the axis of rotation. (a) What is the instantaneous angular velocity of the rod at t = 5 s? (b) What is the angular acceleration of the rod? (c) What is the tangential speed of the beads at t = 5 s? d) What is the tangential acceleration of the beads at t = 5 s? (e) What is the centripetal acceleration of the beads in ? = 5s? Counterclockwise rotation.
