A wheel of diameter 50.0 cm starts from rest and rotates with a constant angular acceleration of 5.00 rad/s2. At the instant the wheel has completed its second revolution, compute the radial acceleration of a point on the rim in two ways. Using the relationship arad = ω2r. From the relationship arad = v2/r.
