# Problem: A student pulls a box 5.0 meters across a horizontal surface at a constant speed of 4.0 meters per second using a force of 60 newtons.a. Calculate the amount of work done by the studentb. What type of energy is being produced by the work done by the student?i. kinetic energy onlyii. potential energy and kinetic energyiii. internal energy and kinetic energyiv. internal energy only

###### FREE Expert Solution

Work done is given by:

$\overline{){\mathbf{W}}{\mathbf{=}}{\mathbf{F}}{\mathbf{·}}{\mathbf{d}}}$, where F is force and d is displacement.

a.

We've been given, F = 60 N
