Ask AI: A 50Kg girl jumps off a 5-meter-high diving board. What is her kinetic energy right before she hits the water?

First, we need to calculate her kinetic energy upon hitting the water, right before impact, assuming no air resistance. The potential energy she had being on the 5m high diving board will be converted into kinetic energy when she falls. Here's the relevant physics behind it: The gravitational potential energy is given by the formula: Potential Energy = mass x gravity x height Substitute the given values: Potential Energy = 50 kg x 9.8 m/s² x 5 m = 2450 Joules The kinetic energy right before hitting the water is equal to the potential energy at the height of the diving board (because of the conservation of energy). So: Kinetic Energy = Potential Energy And therefore, the kinetic energy is 2450 Joules.
