Question

Now use the settings on the simulation to recreate this situation to the best of your ability. Use the purple measuring device to check the actual potential energy when a 70 kg skater is at a height of approximately 5 m. What was the actual potential energy?

Answer 1

The actual potential energy of a 70 kg skater at a height of 5 m is calculated using the formula PE = mgh, and it equals 3430 Joules.

Step-by-step explanation:

The student is asked to calculate the actual potential energy of a 70 kg skater at a height of approximately 5 m. In the context of gravitational potential energy (PE), this is calculated using the formula PE = mgh, where m is the mass (70 kg), g is the acceleration due to gravity (9.8 m/s2 on Earth), and h is the height above the ground (5 m).

By substituting the given values into the formula, we find:

PE = 70 kg × 9.8 m/s2 × 5 m

PE = 3430 Joules

The actual potential energy when the skater is at a height of approximately 5 m is 3430 Joules.
