What cells in the nervous signals travel through the nervous system

A mechanic pushes a 3.60 ✕ 103-kg car from rest to a speed of v, doing 5,130 j of work in the process. during this time, the car moves 21.0 m. neglecting friction between car and road, find v and the horizontal force exerted on the car.
