The rotor of an electric motor has rotational inertia Im about its central axis. The motor is used to change the orientation of the space probe in which it is mounted. The motor axis is mounted along the central axis of the probe; the probe has rotational inertia Ip about this axis. Calculate the number of revolutions of the rotor required to turn the probe through angle θ (measured in radians) about its central axis. State your answer in terms of the given variables, using π when appropriate.

(a) Convert 34.0° to radians, using the appropriate conversion ratio. rad (b) Convert 2.32 rad to degrees. (c) If a circle has radius 1.10 m, what is the arc length subtended by a 34.0° angle? Submit Answer

Please answer C, D, E The angular position of a rod varies as 20.7t2 radians from time t = 0. The rod has two beads on it as shown in the following figure, one at  r1 = 13 cm from the rotation axis and the other at  r2 = 32 cm from the rotation axis. (Note: figure may not be drawn to scale.)   (a) What is the instantaneous angular velocity (in rad/s) of the rod at t = 3 s? (Indicate the direction with the sign of your answer. Round your answer to at least one decimal place.) 1.24.2 rad/s,  ANSWERED (b) What is the angular acceleration (in rad/s2) of the rod at t = 3 s? (Indicate the direction with the sign of your answer.) 41.4  rad/s2,  ANSWERED (c) What are the tangential speeds of the beads (in m/s) at t = 3 s? vt, 1 =16.146 m/s,  ANSWERED vt, 2 =____m/s  (d)What are the tangential accelerations of the beads at t = 3 s?
