A student rides her bicycle down a hill. Together, she and the bicycle have a mass of 56 kilograms. She is moving at 11 meters per second. What is her kinetic energy?

Answer 1

The formula to calculate kinetic energy is:

Kinetic Energy = 0.5 * mass * velocity^2

Given:
mass = 56 kilograms
velocity = 11 meters per second

Substituting the given values into the formula:

Kinetic Energy = 0.5 * 56 kg * (11)^2 m/s
Kinetic Energy = 0.5 * 56 kg * 121 m^2/s^2
Kinetic Energy = 0.5 * 56 kg * 121 m^2/s^2
Kinetic Energy = 0.5 * 6776 kg m^2/s^2
Kinetic Energy = 3388 kg m^2/s^2

Therefore, her kinetic energy is 3388 kg m^2/s^2.
