Question

A wheel with radius 0.50 meters starts rotating at a constant angular acceleration of 0.5 rad/s^2. a) What is the angular velocity of the wheel after 15 seconds? b) The angle through which the wheel rotates during this time? c) The number of revolutions made by the wheel during this time? d) What is the linear velocity of the wheel after 20 seconds? e) What is linear acceleration of the wheel after 20 seconds? omega = omega_0 + alpha t omega^2 = omega_0^2 + 2 alpha theta V = r omega A = r alpha
