Two blocks are connected by massless string that is wrapped around a pulley. Block 1 has a mass m1=6.70m1=6.70 kg, block 2 has a mass m2=2.90m2=2.90 kg, while the pulley has a mass of 2.50 kg and a radius of 25.6 cm. When the pulley turns, there is friction in the axel that exerts a torque of magnitude 0.660 N m. If block 1 is released from rest at a height h=0.800h=0.800 m, how long does it take to drop to the floor?

Question

Two blocks are connected by massless string that is wrapped around a pulley. Block 1 has a mass m1=6.70m1=6.70 kg, block 2 has a mass m2=2.90m2=2.90 kg, while the pulley has a mass of 2.50 kg and a radius of 25.6 cm. When the pulley turns, there is friction in the axel that exerts a torque of magnitude 0.660 N m.

If block 1 is released from rest at a height h=0.800h=0.800 m, how long does it take to drop to the floor?
