The angular position of a rod varies as 234 radians from time ( = 0 . The rod has two beads on it as shown in the following figure, one at 10 cm from the rotation axis and the other at 20 cm from the rotation Rods Counterclockwise rotation Axis of rotation 10 cm 20 cm a. What is the instantaneous angular velocity of the rod at f - 4.5 ? rad/s b. What is the angular acceleration of the rod? 0= rad/42 c. What are the tangential speeds of the beads at t - 1.5 s? m/s m/s d. What are the tangential accelerations of the beads at ! - 4.5st m/l e. What are the centripetal acceleration of the beads at the 4:541a. What is the instantaneous angular velocity of the rod at t = 4.5 s? W rad/s b. What is the angular acceleration of the rod? rad/s2 c. What are the tangential speeds of the beads at t = 4.5 s? Ured m/s Ublue m/s d. What are the tangential accelerations of the beads at t - 4.5 s? at.red m/s at,blue = m/s2 e. What are the centripetal accelerations of the beads at t = 4.5 s? ac.red m/s2 C blun m/ 2
