A 1575 kg car is pulling a trailer of a mass 982kg. If the car and trailer are accelerating at 1.07m/s^2 west, what force is the road exerting on the wheels of the car? What force does the trailer hitch exert on the trailer?
Homework Answers
Solution :
Given :
mass of car (M) = 1575 kg
mass of trailer (m) = 982 kg
acceleration (a) = 1.07 m/s2
what force is the road exerting on the wheels of the car?
Fby road on wheels of car = ( m + M ) a = ( 1575 kg + 982 kg )(1.07 m/s2) = 2735.99 N
What force does the trailer hitch exert on the trailer?
Fby trailer hitch on the trailer = m a = (982 kg)(1.07 m/s2) = 1050.74 N

Problem 3 The mass of the trailer in the figure is 750 kg and is being hitched by a car linked to the trailer at point P. The road is horizontal and the two identical tires can be considered as one, with a single normal reaction and negligible frictional force; the air resistance will also be neglected. (a) Compute the normal force in the tires and the vertical force at point P, when the speed is constant. (b) When the...
