A speedboat with a mass of 529 kg (including the driver) is tethered to a fixed buoy by a strong 30.1 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 boy with the cable supplying all the necessary centripetal force. When the tension of the cable is steady at 12300 N, with what force is the boat's engine pushing the bout? Different physies 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) x v. where v denotes the boat's speed. Ignore any drag force on the cable force: N
A race car rounds one end of a speedway. This end of the track is a turn with a radius of approximately 187 If the track is assumed to be completely flat and the race car is traveling at a comfant 66.00mih around the turn, what is the race car's centripetal (radial) acceleration ? = 5 Convert this result to SI units. What is the force responsible for the centripetal acceleration in this case! friction ravity normal weight
gravity normal O weight To keep from skidding into the wall on the outside of the turn, what is the minimum coefficient of static friction between the race car's tires and the track?
