1. Two people are pushing a stalled car, as the figure indicates. The mass of the car is 1850 kg. One person applies a force of 275 N to the car, while the other applies a force of 395 N. Both forces act in the same direction. A third force of 560 N also acts on the car, but in a direction opposite to that in which the people are pushing. This force arises because of friction and the extent to which the pavement opposes the motion of the tires. Find the acceleration of the car. 275 N 275 N +x 560 N 395 N 395 N Opposing force = 560 N (a) (b) Free-body diagram of the car
