1.	A massive box is dragged along a horizontal floor by a rope. The rope makes an angle of 60^(@) with the horizontal. Find the work done if the tension in the rope is 200 N and the box is moved through a distance of 20 m.
Answer» Solution :Tension T = 200 N , distance S = 20 m , `THETA = 60^(@)` Work DONE W = Fs = Fs `COS theta = (F cos theta). S = 200 xx cos 60^(@) xx 20 = 2000 J`
