An SUV pulls a trailer carrying a boat. The mass of the SUV is 2490 kg and the mass of the boat and trailer is 510 kg. The SUV starts from rest (velocity = 0) and accelerates for 10 seconds to final velocity 12 m/s; i.e., a = 1.2 m/s2.
(a) During the acceleration, what is the force on the boat and trailer? (A positive force means a force in the direction of motion.)
(b) What is the force exerted by the trailer on the SUV?
(c) What is the net force on the SUV?
(d) What is the frictional force exerted by the road on the tires of the SUV?
