A flywheel with a radius of 0.260 meter starts from rest and accelerates with a constant angular acceleration of 0.750 rad/s2.
Part A: Find the magnitude of the tangential acceleration, the radial acceleration, and the resultant acceleration of a point on its rim at the start.
Part B: Find 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 degree?
Part C: Find 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 degree?
