In the figure below, the hanging object has a mass of m1 = 0.355kg; the sliding block has a mass of m2 = 0.880 kg; and the pulleyis a hollow cylinder with a mass of M = 0.350 kg, an inner radiusof R1 = 0.020 0 m, and an outer radius of R2 = 0.030 0 m. Assumethe mass of the spokes is negligible. The coefficient of kineticfriction between the block and the horizontal surface is µk =0.250. The pulley turns without friction on its axle. The lightcord does not stretch and does not slip on the pulley. The blockhas a velocity of vi = 0.820 m/s toward the pulley when it passes areference point on the table.

(a) Use energy methods to predict its speed after it has moved to asecond point, 0.700 m away.
(b) Find the angular speed of the pulley at the same moment.
