While painting the walls of his house, a person stands on a ladder holding a bucket containing paint in one hand and a brush in the other. Suddenly, the bucket slips from his grasp and falls to the floor. If the bucket with the paint possessed a mass of 6.0 kg and was at a height of 2.0 m when it slipped, how much gravitational potential energy is lost together with the paint?

Options

  1. A59 J
  2. B120 J
  3. C118 J
  4. D235 J

Correct answer

C. 118 J

Step-by-step solution

The loss in gravitational potential energy is given by: U = mgh Substituting the given values m = 6.0 kg , h = 2.0 m , and g = 9.8 m/s ^2 : U = 6.0 9.8 2.0 U = 117.6 J Rounding to the nearest integer, the lost gravitational potential energy is 118 J .
