# the moment of inertia of a flywheel

Science

A 51.4 cm diameter disk rotates with a constant angular acceleration of 2.50 rad/s^2. It starts from rest at t= 0, and a line drawn from the center of the disk to a point P on the rim of the disk makes an angle of 57.3 degrees with the positive x axis at this time.

(a) Find the angular speed of the wheel at t=2.30 s.

(b) Find the linear velocity and tangential acceleration of P at t=2.30s.

(c) Find the position of P (in degrees, with respect to the positive x axis) at t=2.30 s.
