A block A of mass 80kg is connected by a light, inextensible rope to a block B of mass 40kg. The rope joining the two blocks is taut and is parallel to a line of greatest slope of a plane which is inclined at an angle of 20° to the horizontal. A force of magnitude 500N inclined at an angle of 15° above the same line of greatest slope acts on A [Figure X.X]. The blocks move up the plane and there is a resistance force of 50N on B, but no resistance force on A.
