Question
A box of weight w=2.0N accelerates down a rough plane that is inclined at an angle =30 above the horizontal, as shown (Figure 6) . The normal force acting on the box has a magnitude n=1.7N, the coefficient of kinetic friction between the box and the plane is k=0.30, and the displacement d of the box is 1.8 m down the inclined plane.
What is the work Ww done on the box by the weight of the box?
A box of weight w=2.0N accelerates down a rough plane that is inclined at an angle I =30a above the horizontal, as shown (Figure 6) . The normal force acting on the box has a magnitude n=1.7N, the coefficient of kinetic friction between the box and the plane is 1/4k=0.30, and the displacement da of the box is 1.8 m down the inclined plane. What is the work Ww done on the box by the weight of the box?Explanation / Answer
Vertical distance = 1.8 sin 30
= 0.90 m
W = 2.0 N * 0.90 m
= 1.80J
