17. [0/8 Points] DETAILS The angular position of a rod varies as 24.2t² radians from time t = 0. The rod has two beads on it as shown in the following figure, one at r₁ = 11 cm from the rotation axis and the other at r₂ = 34 cm from the rotation axis. (Note: figure may not be drawn to scale.) Counterclockwise rotation PREVIOUS ANSWERS OSUNIPHYS1 10.1.P.036. Axis of rotation 11 cm (a) What is the instantaneous angular velocity (in rad/s) of the rod at t = 7 s? (Indicate the direction with the sign of your answer. Round your answer to at least one decimal place.) 169.4 X rad/s Vt, 1 Vt, 2 = (b) What is the angular acceleration (in rad/s²) of the rod at t = 7 s? (Indicate the direction with the sign of your answer.) rad/s² 34 cm (c) What are the tangential speeds of the beads (in m/s) at t = 7 s? m/s m/s = (d) What are the tangential accelerations of the beads at t = 7 s? (Enter the magnitudes in m/s².) at, 1 m/s² at, 2 = m/s² (e) What are the centripetal accelerations of the beads at t = 7 s?
