To paint the side of a building, painter normally hoists himself up by pulling on the rope A as in figure. The painter and plateform together weigh 200 N. The rope B can withstand 300 N. Then

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.

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.

A 60kg painter on a 15 kg platform. A rope attached to the platform and passing over an overhead pulley allows the painter to raise himself along with the platform. To get started, he pulls the rope down with aforce of 400N. Find the acceleration of the platform as well as that of the painter.

Figure shows a boy on a horizontal platform A on a smooth horizontal surface, holding a rope attached to a box B. Boy pulls the rope with a constant force of 50 N. The combined mass of platform A and boy is 250kg and that' of box B is 500kg. The velocity of A relative to the box B 5 s after the boy on A begins to pull ,the rope,will be: (A) 1 m/s (B) 2 m/s (C) 0.5 m/s (D) 1.5 m/s

In the a painter of mass 100 kg pulls himself up with the crate with a n acceleration if the painter exerts, an effective force of 450 N on the floor of the crate, find (a) the acceleration of the painter and (b) the tension in the string taking g=10 m//s^(2)
