Help science project due tomorrow -- Figure Skater Jump Hello, I need help on my physics project that is dues tomorrow. The project is about the energy conservation of a figure skater doing a waltz jump. There are four stages that I explain her kinetic, potential and total energy. For stage four, the figure skater lands on the ice. Her energy is converted into kinetic energy. However, some of her energy goes into the vibrations of the ice. Eventually the skater will put her foot down and slide it on the ice to stop moving. The energy will turn into heat. I was wondering how to calculate how much energy goes into the ice, and how much kinetic energy she has when she lands. Here is some information- the figure skater weighs 45 kg. The total energy for the first three stages is 157.5 J. In the second stage when the figure skater has maximum kinetic energy, her velocity is 2.65^2. If anyone could post anything helpful, soon, it would be greatly appreciated.
