1200-kg car pulls a boat on a trailer. (a) What total force resists the motion of the car, boat,
and trailer, if the car exerts a 2000-N force on the road and produces an acceleration of 0.5
m/s2 & the mass of the boat plus trailer is 800 kg. (b) What is the force in the hitch between
the car and the trailer if 80% of the resisting forces are experienced by the boat and trailer?
