Two buckets of mass m1=20.1 kg and m2=11.9 kg are attached to the ends of a massless rope which passes over a pulley with a mass of mp=7.33 kg and a radius of rp=0.150 m. Assume that the rope does not slip on the pulley, and that the pulley rotates without friction. The buckets are released from rest and begin to move. If the larger bucket is a distance d0=1.65 m above the ground when it is released, with what speed v will it hit the ground?

Electromagnetic induction. a coil of wire contains n turns and has an electrical resistance r. the radius of each turn is a. initially, inside the coil there exists a uniform magnetic field of magnitude b0 parallel to the axis of the coil. the magnetic field is then reduced slowly. the current induced in the coil is i. how long does it take for the magnitude of the uniform field to drop to zero?
