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], A. what's the magnitude of the tangential acceleration of the wheel’s rim? B. what's the angular speed of the wheel’s rim? c. what's the tangential speed of the wheel’s rim? 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?

A. what's the magnitude of the tangential acceleration of the wheel’s rim?
B. what's the angular speed of the wheel’s rim?
c. what's the tangential speed of the wheel’s rim?
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?
