You are moving the box (m=10kg) across a rough floor by pushing on it at an angle of 20° below the horizontal with force
of magnitude F=100N. What is the coefficient of kinetic friction between the box and the floor if it is moving at constant
velocity? Present free-body diagram.

For a situation as in problem 2, calculate work done by you, work done by the force of friction and the net work done if
crate was moved 5m.
