Danny Diver weighs 500 N and steps off a diving board 10 m above the water. Danny hits the water with kinetic energy of

Question

Quizplus · Accepted Answer

Danny's potential energy at the height of 10 m is converted into kinetic energy as he falls. The potential energy (PE) can be calculated using the formula PE = mgh, where m is mass in kilograms, g is the acceleration due to gravity (9.8 m/s^2), and h is the height in meters. Since weight (W) is the force of gravity on an object and can be calculated by W = mg, we can rearrange this to find m = W/g. Substituting Danny's weight (500 N) for W and using 9.8 m/s^2 for g, we find his mass. Then, using h = 10 m, we calculate his potential energy at the top, which equals his kinetic energy just before hitting the water. The calculation shows that his kinetic energy is 5000 J.
