Question

A 630 kg car pulling a 500 kg trailer accelerates forward at a rate of 2.17 m/s². Assume frictional forces on the trailer are negligible. Ignore air drag.

(a)

Calculate the net force (in N) on the car.

magnitude N direction ---Select--- forward backward

(b)

Calculate the net force (in N) on the trailer.

magnitude N direction ---Select--- forward backward

(c)

What is the force (in N) exerted by the trailer on the car?

magnitude N direction ---Select--- forward backward

(d)

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.)

magnitude N direction ° (measured from the left of the −y-direction)
