 Do you think the Skater will make it over the first hump?
(No friction on the track)

• No, because his potential energy will be converted to thermal energy
• No, because he doesn’t have enough potential energy
• Yes, because all of his potential energy will be converted to kinetic energy
• Yes, because some of his energy will be potential and some kinetic
