A man sits on a chair supported by a rope passing over a frictionless fixed pulley. The man who weighs `1,000N` exerts a force of `450N` on the chair downwards while pulling the rope on the other side. If the chair weighs `250N` then the acceleration of the chair is .

As shown in the given figure, two blocks are connected by a rope that passes over a set of pulleys. One block has a weight of 412 N, and the other has a weight of 908 N. The rope and the pulleys are massless and there is no friction. What is the acceleration of the lighter block ?

A man sits in a chair that is suspended from arope. The rope passes over a pulley suspended from the ceiling, and the man holds the other end of the rope in his hands.What is the tension in the rope, and what force does the chair exert on the man ?

A chair weighing 60 N is lifted to a height of 0.8 m and then carried 6 m across the room. How much work is done on the chair?

Figure represents a painter in a crate which hangs alongside a building. When the painter of mass 100kg pulls the rope, the force exerted by him on the floor of the crate is 450N . If the crate weighs 25 kg. find the acceleration (in ms^(-2) ) of the painter.
