1. Do you think the Skater will make it over the first hump? (No friction on the track) A. No, because his potential energy will be converted to thermal energy B. No, because he doesn’t have enough potential energy C. Yes, because all of his potential energy will be converted to kinetic en...

1. Do you think the Skater will make it over the first hump? (No friction on the track) A. No, because his potential energy will be converted to thermal energy B. No, because he doesn’t have enough potential energy C. Yes, because all of his potential energy will be converted to kinetic energy D. Yes, because some of his energy will be potential and some kinetic  2. Do you think the Skater will make it over the first hump? (lots of track friction) A. No, because his potential energy will be converted to thermal energy B. No, because he doesn’t have enough potential energy C. Yes, because all of his potential energy will be converted to kinetic energy D. Yes, because some of his energy will be potential and some kinetic  3. Do you think the Skater will make it over the first hump? (No friction on the track) A. No, because his potential energy will be converted to thermal energy B. No, because he doesn’t have enough potential energy C. Yes, because all of his potential energy will be converted to kinetic energy D. Yes, because some of his energy will be potential and some kinetic  4. Do you think the Skater will make it over the first hump? (lots of track friction) A. No, because his potential energy will be converted to thermal energy B. Yes, if not too much energy is converted to thermal C. Yes, because all of his potential energy will be converted to kinetic energy D. Yes, because some of his energy will be potential and some kinetic  5.
