Physics Work and Energy Question!
A boy pulls a 10.0 kg book rack at rest on a smooth floor with a constant horizontal force of 1.2N starting from rest.
Compute the change in kinetic energy of the box after the boy has pulled it a distance of 5.0m
compute the final velocity of the box after the boy has pulled it a distance of 5.0m.
I have no idea where to even start. Help would be massively appreciated. Thank you in advance.
