2. A block with a mass of 5.00 kg slides down a surface inclined at 36.9° from horizontal, attached to a string wrapped around a flywheel, as shown in the figure. The flywheel has a mass of 8.50 kg and a radius of 30.0 cm, and rotates freely about its central axis. Assume there is no friction between the block and the surface. [A disk of radius R and mass M has 1 = MR² about its axis.] O ·m 5.00 kg 36.9° a. Find the magnitude of the block's acceleration down the ramp. b. Find the tension in the string. c. Find the angular velocity of the flywheel after the mass has slid 2.00 m down the incline.
