Question

Do the bicycle and rider have energy when they’re positioned at the top of the hill? If so, try to explain your answer.

Answer 1

Yes. At the top of the hill they have potential energy. while riding down the hill the bike will pick up speed.

Answer 2

Yes, the rider and bicycle have energy at the top of the hill. That’s because they move without pedaling when the brake is released. If the rider and bicycle were at the bottom of the hill, just releasing the brake wouldn’t create motion. The rider would need to pedal.
