Question: A car is towing a boat on a trailer. The driver starts from rest and accelerates to a velocity of +19.9 m/s in a time of 28.9 s. The combined mass of the boat and trailer is 528 kg. The frictional force acting on the trailer can be ignored.
Part A: What is the tension in the hitch that connects the trailer to the car?
I need help to find the tension in the hitch that connects the trailer to the car.
