Hello I need help on these two questions provided in the image. (if the question is too long, only doing one of them would work as well to not take up a lot of your time!) Thank you so much!

The cord goes over a pulley with a mass of M = 0.350 kg. The pulley can be modeled as a hollow cylinder with an inner radius of R1 = 0.0200 m, and an outer radius of R2 = 0.0300 m; the mass of the spokes is negligible. As the weight falls, the block slides on the table, and the coeffcient of kinetic friction | between the block and the table is \"k = 0.250. At the instant shown, the block is moving with a velocity of VI- = 0.820 m/s toward the pulley. Assume that the pulley is free to spin without friction, that the cord does not stretch and does not slip on the pulley, and that the mass of the cord is negligible. (3) Using energy methods, find the speed of the block (in m/s) after it has moved a distance of 0.700 m away from the initial position shown. l1.o45 x Use consewation of energy, treating the universe as the system of interest. What types of energy are changing? How do you relate the kinetic energy of the pulley to its moment of inertia and angular speed? What is the moment of inertia of a hollow cylinder? How is the angular speed related to the linear speed of the block? What is the internal energy change of the system, and how is it related to friction? m/s (b) What is the angular speed of the pulley (in rad/s) after the block has moved this distance? l% x How is angular speed related to linear speed? What is the final speed of the block found in part (a)? rad/s MN\": Unlpx') lW
