What is the kinetic energy of a 62kg cyclist if she is moving on her bicycle at 8.2 m/s?
The formula for kinetic energy is
(1/2) M V^2
M is mass and V is velocity.
If you do not have a calculator and need one, you can use Google.

To calculate the kinetic energy of an object, you can use the equation:
Kinetic Energy = 1/2 * mass * velocity^2
In this case, the mass of the cyclist is 62 kg and her velocity is 8.2 m/s.
Substituting these values into the equation:
Kinetic Energy = 1/2 * 62 kg * (8.2 m/s)^2
To solve this, you need to perform the calculations step by step:
1. Square the velocity:
(8.2 m/s)^2 = 67.24 m^2/s^2
2. Multiply the squared velocity by the mass:
67.24 m^2/s^2 * 62 kg = 4161.28 kg·m^2/s^2
3. Multiply the result by 1/2:
4161.28 kg·m^2/s^2 * 1/2 = 2080.64 kg·m^2/s^2
Therefore, the kinetic energy of the cyclist is approximately 2080.64 kg·m^2/s^2.
