A speedboat with a mass of 545 kg545 kg (including the driver) is tethered to a fixed buoy by a strong 32.7 m32.7 m cable. The boat's owner loves high speed, but does not really want to go anywhere. So the owner revs up the boat's engine, makes a lot of noise, and runs the boat in circles around the buoy with the cable supplying all the necessary centripetal force. When the tension of the cable is steady at 13700 N,13700 N, with what force is the boat's engine pushing the boat? Different physics textbooks treat drag force somewhat differently and use different formulas. For the present purpose, take the water's drag force on the boat to be (450 kg/m)×?2,(450 kg/m)×v2, where ?v denotes the boat's speed. Ignore any drag force on the cable.

A metal seat with mass m1 = 16 kg hangs from one end of a rope that passes over a frictionless pulley attached to the ceiling. A spring scale hangs from the other end of the rope. A girl with mass m2 = 34 kg sitting on the hung seat is pulling the spring scale. The total system is in static equilibrium state. Question:(1) how much does the scale reads(in Newton)? (2). what is the support force of the seat to the girl? (hint 1: write down all the forces exerted on the chair and on the girl separately and demand the net force for each is zero. hint 2: Newton’s third law says that if there is a force exerted on A by B, then there must be another force exerted on B by A with the same magnitude and in opposite direction)
