at the top of a hill, an athlete on a skateboard has x joules of mechanical energy. how much mechanical energy will she have at the bottom of the hill? ignore the effects of friction.\nx joules\nless than x joules\nmore than x joules\nthere is not enough information to know.

Answer

Brief Explanations:

According to the law of conservation of mechanical energy (in the absence of non - conservative forces like friction), the total mechanical energy of a system remains constant. Here, with friction ignored, the athlete's mechanical energy at the top of the hill will be the same as at the bottom.

Answer:

A. X joules
