Do you think the skater will make it over the first hump? (lots of track friction)

• 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.
