By the work-energy theorem the work done by a force equals the change in kinetic energy, so the work here is half of 4 kilograms times 5 metres per second squared, that is 0.5 into 4 into 25, which gives 50 joules.

Work done is force multiplied by the displacement along the force, so F equals the work divided by the distance, that is 480 joules divided by 15 metres, which gives 32 newtons.
