Question

Three students are about to dive from the high boards into the pool. The boys are on diving boards that are 3 m above the water, and the girl is on a board that is 5 m above the water. Using the picture as a model of energy levels, which of these has the MOST gravitational potential energy AND explain HOW YOU KNOW. (hint: think about what is true about things with a large potential energy…)

Answer 1

Step-by-step explanation:

Given that there are boys (plural) only at a height of 3 meters, they still might have more energy than a single girl.

The girl might have a mass of 50 to 60 kg. The boys will likely have slightly more.

Girl PE

PE = 5 * 50 * 10

PE = 2500 N

Boys

PE = 3 * 120 * 10

PE = 3600 N

That's with 2 boys on the 3 meter board. The girl would have a PE more than 1 boy likely or possibly.
