potential energy/ momentum

Question

A man does 4,550 J of work in the process of pushing his 2.60  10³ kg truck from rest to a speed of v, over a distance of 27.0 m. Neglecting friction between truck and road, determine the following.

the speed v ?(in m/s)

the horizontal force exerted on the truck? (in N)

Answer 1

Assuming all the work w goes into kinetic energy, then w = mv²/2 can be solved for v. Assuming the force f is constant over the distance d, then w = fd can be solved for f.
