Question

A bicycle wheel 67.0 [cm] in diameter rotates about its central axis with a constant angular acceleration of 4.48 [rad/s2]. It starts from rest at time t =0 [s], and a reference point on the wheel's rim P makes an angle of 60.0° above the horizontal at this time. When the wheel starts rotating, at time t=3.70 [s],

A. what is the magnitude of the tangential acceleration of the wheel's rim?

B. what is the angular speed of the wheel's rim?

C. what is the tangential speed of the wheel's rim?

D. what is point P's new angular position from the horizontal in radians?

At t=1.50 [s], a small, 92.5 [g] pebble got stuck on the rim of the wheel.

E. What is the pebble's moment of inertia with respect to the wheel's axis of rotation?

F. At t=3.70 [s], what is the pebble's rotational kinetic energy?
