A bicycle wheel 65.0 [cm] in diameter rotates about its central axis with a constant angular acceleration of 4.50 [rad/s2]. It starts from rest at time ? = 0 [s], and a reference point on the wheel’s rim ? makes an angle of 50.0◦ above the horizontal at this time. When the wheels starts rotating, at time ? = 2.70 [s], d. what's point ?’s new angular position from the horizontal in radians? At ? = 1.40 [s], a small, 93.5 [g] pebble got stuck on the rim of the wheel. e. What's the pebble’s moment of inertia with respect to the wheel’s axis of rotation? f. At ? = 2.70 [s], what is the pebble’s rotational kinetic energy?
