The potential energy of an object is given by the formula:
Potential Energy = mass * gravity * height
Plugging in the given values:
Potential Energy = 60 kg * 9.8 m/s² * 5 m
Potential Energy = 2940 J
Therefore, the potential energy of the skateboarder is 2940J.
The correct answer is B. 2940J.
Potential Energy = mass * gravity * height
Plugging in the given values:
Potential Energy = 60 kg * 9.8 m/s² * 5 m
Potential Energy = 2940 J
Therefore, the potential energy of the skateboarder is 2940J.
The correct answer is B. 2940J.
