A mechanic pushes a 2.40 x 103-kg car from rest to a speed of v, doing 4,920 J of work in the process. During this time, the car moves 24.0 m. Neglecting friction between car and road, find v and the horizontal force exerted on the car. (a) the speed v m/s (b) the horizontal force exerted on the car (Enter the magnitude.)
