Answer:
Explanation:
The gravitational potential energy (GPE) of an object with mass m at a height h above some reference level is given by the formula:
GPE = mgh
where g is the acceleration due to gravity (which is approximately 9.8 m/s^2 on Earth).
In this case, the snowboarder has a mass of 55.0 kg and is at a height of 4.50 m above some reference level (which is not specified). So the GPE of the snowboarder is:
GPE = (55.0 kg) x (9.8 m/s^2) x (4.50 m) = 2404.5 J
Therefore, the gravitational potential energy of the snowboarder is 2404.5 joules (J).
