A mechanic pushes a 2.50 x 10^{3}- kg car from rest to a speed of v,

doing 5.00 x 10^{3} J of work in the process. During this time, the

car moves 25.0 m. Neglecting friction between car and road,

find (a) v and (b) the horizontal force exerted on the car.

Step 1

(a)

The work done by the kinetic energy = kinetic energy of the car

Step 2

Rearrange the above equation to obtain an equation for ...
