A skier with a mass of 84 kg hits a ramp of snow at 32 m/s and becomes airborne. At the highest point of flight, the skier is 4.7 m above the ground. What is the skier's gravitational potential energy at this point?

Answer :

Final answer:

The skier's gravitational potential energy at the highest point of flight is 3847.92 Joules.

Explanation:

The skier's gravitational potential energy at the highest point of flight can be calculated using the equation:

Gravitational Potential Energy = mass × gravitational acceleration × height

Given that the skier's mass is 84 kg, the gravitational acceleration is 9.8 m/s², and the height is 4.7 m, we can calculate the gravitational potential energy:

Gravitational Potential Energy = 84 kg × 9.8 m/s² × 4.7 m

Gravitational Potential Energy = 3847.92 J

Therefore, the skier's gravitational potential energy at the highest point of flight is 3847.92 Joules.
