A 10 kg block is pushed 20.0 m up the sloping surface of a plane inclined at an angle of 37o to the horizontal by a constant force F of 110.0 N acting parallel to the plane as shown in figure 2 below. The coefficient of kinetic friction between the block and plane is 0.25. Calculate work done by friction

m=10kg
h=20m
μ=0.25
α=37°
F=110N
we introduce the coordinate system:
X-axis parallel to the slope of the inclined plane
