A 75.0-kg person climbs stairs, gaining 2.50 meters in height. Find the work done to accomplish this task.

Solution 2PE

Work is done against gravity here and the person gains a height. Therefore, the work done here is equal to potential energy and the mathematical expression for potential energy is , is the mass of the person, is the acceleration due to gravity and is the height gained by the person.

Step 1 of 2

Given data:

Mass of the person kg

Height m

Acceleration due to gravity m/s2
