Figure represents a painter in a crate which hangs alongside a building. When the painter of mass 100 kg pulls the rope, the force exerted by him on the floor of the crate is 450 N. If the weight of the crate is 25 kg , the acceleration of the painter will be : ( Take $g = 10 m / s^{2}$ )

Question

TestHub · Accepted Answer

Force exerted by the painter on the floor of the crate $= 450 N$ (given)

Net force exerted by the floor of the crate on the paiter

$= 450 - 25 g = 450 - 25 \times 10 = 200 N .$

If a is the upwards acceleration of the painter (mass $= 100 kg$ )

$100 a = 200 a = 2 m / s^{2}$
