A trailer mechanic pushes a 2500 kg car, home to a speed v, performing a job during the 5000 J. In this process, the car moves 25 m. Neglecting friction between the car and roadway:

(A) What is the final velocity v of the car?

(B) What horizontal force exerted on the car?

A) 1/2mv^2 - 1/2 mv^2= work

The first is the final KE

The second is the initial KE which = 0 since it was at rest
