A 620 kg car pulling a 490 kg trailer accelerates forward at a rate of 2.18 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.)
