A safe with a weight of 2000N is pushed across a tiled floor with constant velocity of 1.5m/s for a distance 10m. the coefficient of friction between the bottom of the scale and the floor is 0.5.
a) identify the four forces acting on the case
b) calculate the work done by each of these forces
c) what is the total work done, combing all these forces, and the total power dissipated?
could you show the working out and stuff plz
thanks for the help

Could you show your attempt first?
What exactly are you having trouble with?
I imagine you can identify most if not all of those forces.
I would be pleased to help but it's nice to see that someone has made some effort first.
