When using the zip wire, the person moved through a vertical height of 2.0 m.
The person has a mass of 45 kg.
gravitational field strength = 9.8 N/kg.
Calculate the change in gravitational potential energy of the person.
Use the equation:
gravitational potential energy = mass × gravitational field strength × height

Gravitational potential energy (GPE) is the energy an object has due to its position in a gravitational field. The change in GPE is calculated when an object moves vertically. The equation is: ΔGPE = m × g × Δh Where: - m = mass (45 kg) - g = gravitational field strength (9.8 N/kg) - Δh = change in vertical height (2.0 m) Substituting the values: ΔGPE = 45 × 9.8 × 2.0 ΔGPE = 441 × 2.0 ΔGPE = 882 J
