A mechanic pushes a 3.10 x 10³-kg car from rest to a speed of v, doing 5,040 J of work in the process. During this time, the car moves 22.0 m. Neglecting friction between car and road, find v and the horizontal force exerted on the car. (a) the speed v 6.774 Your response differs from the correct answer by more than 100%. m/s (b) the horizontal force exerted on the car (Enter the magnitude.) 229.09 N
