A disc of radius 50.0cm is rotating at 120 rpm, and its angular acceleration is 3.00 rad/s^2. Find the magnitudes of the velocity, v, and tangential acceleration, a, of its outer edge.
Convert 120 rpm to radians per second (w).
The velocity is V = R w.
The tangential acceleration is
R*3.00 rad/s^2.
R = 0.500 m
