A car is towing a boat on a trailer. The driver starts from rest and accelerates to a velocity of 12.0 m/s in a time of 25.0 s. The mass of the boat and the trailer is 400 kg and the mass of the car is 900 kg. Assume that the frictional force on the trailer is negligible.
A) What is the acceleration of the car and trailer?
B) What is the tension in the hitch that connects the trailer to the car?
C) What is the net force on the car( magnitude and direction)?
D) What is the magnitude and the direction of the friction force acting on the car point?
