Worth 50 points, please answer quick.

A snowboarder stands at the edge of a 4.50 m high half-pipe. The mass of the snowboarder is 55.0 kg. What is the gravitational potential energy of the snowboarder?

Answer 1

he gravitational potential energy of the snowboarder is 2532.5 J.

Step-by-step explanation:

The gravitational potential energy of an object is given by the formula:

PE = mgh

where m is the mass of the object, g is the acceleration due to gravity, and h is the height of the object.

In this case, the mass of the snowboarder is 55.0 kg, the acceleration due to gravity is 9.8 m/s^2, and the height of the snowboarder is 4.50 m. So, the gravitational potential energy of the snowboarder can be calculated as:

PE = (55.0 kg)(9.8 m/s^2)(4.50 m) = 2532.5 J

So, the gravitational potential energy of the snowboarder is 2532.5 J.

Answer 2

2425.5 J

Step-by-step explanation:

The gravitational potential energy of an object can be calculated using the formula:

PE = m * g * h

where PE is the potential energy, m is the mass of the object, g is the acceleration due to gravity (9.8 m/s^2 on the surface of the Earth), and h is the height of the object above a reference point.

Plugging in the values, we get:

PE = 55.0 kg * 9.8 m/s^2 * 4.50 m = 2425.5 J

So the gravitational potential energy of the snowboarder is 2425.5 J (joules).
