A car is towing a boat on a trailer. The driver starts from rest and accelerates to a velocity of +15.4 m/s in a time of 27.5 s.
The combined mass of the boat and trailer is 584 kg. The frictional force acting on the trailer can be ignored. What is the tension in the hitch that connects the trailer to the car?
Explanation: Tremendous heat and pressure within the earth cause the hot magma to flow in convection currents. These currents cause the movement of the tectonic plates that make up the earth's crust.
