In a horizontal uniform circular motion, is the centripetal force acting on the stopper provided by the tension in the string, always equal to the weight of the hanging mass?
A motorist travels along a vertical circle with a diameter of 10.0 m. After one successful revolution, he notices that his speed at the bottom of the pathway is 6.50 m/s. The mass of the motorists is 70.0 kg.
What apparent weight would he feel?
An owner of a speedboat loves high speed but doesn't want to go anywhere. So he tethers the speedboat to a fixed buoy by a strong cable of length 40.0 m40.0 m, which supplies all the centripetal force to run the boat in circles around the buoy. When the tension in the cable is steady at 13500 N13500 N, with what force is the boat's engine pushing the boat? Assume that the mass of the speedboat (including the driver) is 645 kg645 kg. Take the water's drag force to be (450 kg/m)×v2(450 kg/m)×v2, where vv denotes the boat's speed. Ignore any drag force on the cable. Be sure to include the free-body diagram for the boat.
