A 45 kg person jumps off a diving platform 10.0 m above the water. If they reach the surface of the water at a speed of 12 m/s what is the person's kinetic energy
The formula for kinetic energy is:
Kinetic Energy = 1/2 * mass * velocity^2
Given that the person's mass is 45 kg and their velocity is 12 m/s, we can substitute these values into the formula:
Kinetic Energy = 1/2 * 45 kg * (12 m/s)^2
Simplifying this equation:
Kinetic Energy = 1/2 * 45 kg * 144 m^2/s^2
Kinetic Energy = 3240 kg * m^2/s^2
So, the person's kinetic energy is 3240 kg * m^2/s^2.
