Two objects with masses m1 = 20kg and m2 = 12kg are connected to a pulley in the shape of a disk with a radius of R = 0.2m and a mass of M = 16kg. Initially, m2 is placed on the ground and m1 is at rest 4m above the ground. (Note that the mass of the string can be ignored and the pulley does not slip. The moment of inertia of the disk about its center of mass is 1 = (1/2)MR^2, and the magnitude of the gravitational acceleration is 10m/s ^2.)" (a) What is the magnitude of the acceleration of m2 while m1 falls a distance of 4 meters? (b) What is the velocity of m1 when it reaches the ground?
