Question: The two blocks in the figure are connected by a mass less rope that passes over a pulley. The pulley is 17cm in diameter and has a mass of 1.9kg. As the pulley turns, friction at the axle exerts a torque of magnitude 0.70Nm.
Part A: If the blocks are released from rest, how long does it take the 4.0 kg block to reach the floor?
I want help to find how long it takes the 4.0 kg block to reach the floor.
