Question

A 630 kg car pulling a 530 kg trailer accelerates forward at a rate of 2.11 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- (b) Calculate the net force (in N) on the trailer. magnitude N direction -Select- (c) What is the force (in N) exerted by the trailer on the car? magnitude N direction -Select- (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)
