Activity:

3. Consider the system given below: T 2 171 M Assume m = 1.0 kg, M = 2.0 kg, and 0 = 30. Neglect any rotational and frictional effect of the pulley. Assume the masses are released from rest. Find: (a) the acceleration a of the system and the tensions Ti and Tz using Newton's 2nd Law of Motion; (b) the final velocities v1 of M, vz of m, and v3 of 2m when M has moved (which way?) 10 cm using Kinematics; (c) the final speeds v1 of M, v2 of m, and v3 of 2m when M has moved 10 cm using the Work- Energy Theorem, and (d) ) the final speeds vi of M, v2 of m, and v3 of 2m when M has moved 10 cm using the Principle of Conservation of Mechanical Energy
