Problem 29PE

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.

Given data:

Mass of the car

Mass of trailer and boat combined,

Acceleration of the system
