A painter of mass 70 kg climbs 3.0 m up a ladder. The painter's potential energy has increased by

Question

Quizplus · Accepted Answer

The formula for potential energy is:
PE = mgh
Where m is the mass of the object, g is the acceleration due to gravity (9.81 m/s^2), and h is the height the object has been raised.

Plugging in the values given in the problem, we get:
PE = (70 kg)(9.81 m/s^2)(3.0 m)
PE = 2058 J

Therefore, the painter's potential energy has increased by 2058 J. The correct choice is A).
