Good evening.

I would appreciate if someone could verify the following please.

The question:

A 100kg crate is pulled across a horizontal floor by a force P that makes an
angle of 30 degrees above the horizontal. The coefficient of kinetic
friction between the crate and floor is 0.200. What is P if the net work
done is zero.

My solution:

First determine Ff = umg. This would give me 196N. My next step is to
determine P. I use 196N and put that over cos30. My answer is 226.3N. Does
this seem reasonable.

thanks for your time
