A 630 kg car pulling a 470 kg trailer accelerates forward at a rate of 2.15 m/s2. Assume frictional forces on the trailer are negligible. Ignore air drag.

What is the resultant force exerted by the car on the road? (Assume that the forward direction is along the +x-direction to the right and that the +y-direction points upward. Enter the magnitude in N and the direction in degrees measured from the left of the −y-direction.)

A 1700-kg truck and a 1000-kg car are parked with their rear bumpers nearly touching each other in a level parking lot. Both vehicles have their brakes off so that they are free to roll. A man sitting on the rear bumper of the truck exerts a constant horizontal force on the rear bumper of the car with his feet, and the car accelerates at 1.2 m/s2. Ignore any friction between the tires and the parking lot surface. The direction...

12) There are several types of drag on a car other than air resistance. Effects having to do with the squeezing of the tires (rolling resistance) and frictional forces in the drivetrain (the system that transfers energy from the engine to the rotation of the wheels) also must be taken into account. Engineers use the following equation to model the total force due to these different effects Fdrag=A+Bv+Cv2Fdrag=A+Bv+Cv2 For a Camry, these coefficients are estimated to be A=117.130A=117.130 N, B=1.800...
