Question

While riding a chairlift, a 55-kilogram skier is raised a vertical distance of 370 meters. What is the total change in the skier's gravitational potential energy

Answer 1

The change in the skier's gravitational potential energy is 199430 J.

Gravitational potential energy:

This is the energy of a body due to its position in a gravitational field. The  S.I unit of gravitational potential energy is Joules (J)

The Change in the skier's gravitational potential energy can be calculated using the formula below.

Formula:

• ΔP.E = mg(Δh)............... Equation 1

Where:

• ΔP.E = Change in the skier's potential energy
• m = mass of the skier
• Δh = change in height to which it was raised
• g = acceleration due to gravity.

From the question,

Given:

• m = 55 kg
• Δh = 370 m

• g = 9.8 m/s²

Substitute these values into equation 1

• ΔP.E = 55×370×9.8
• ΔP.E = 199430 J.

Hence, The change in the skier's gravitational potential energy is 199430 J.
