A mechanic pushes a 2.20 ✕ 103-kg car from rest to a speed of v, doing 4,530 J of work in the process. During this time, the car moves 27.0 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.)
