Question: A flywheel with a radius of 0.300m starts from rest and accelerates with a constant angular acceleration of 0.600rad/s2 .
A) Compute the magnitude of the tangential acceleration, the radial acceleration, and the resultant acceleration of a point on its rim after it has turned through 60.0?.
B) Compute the magnitude of the tangential acceleration, the radial acceleration, and the resultant acceleration of a point on its rim after it has turned through 120?.
