A 1100-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 1900-N force on the road and produces an acceleration of 0.550 m/s2 ? The mass of the boat plus trailer is 700 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?
Solution to 29PE
Step 1 of 3
We need to find the force which resists the movement of the car, trailer-boat system if the car pulls the trailer by a force of 1900N with an acceleration of . We are also asked to find the force in the tug line between the car and the trailer.
Mass of the car
Mass of trailer and boat combined,
Acceleration of the system
