Answer 1

To calculate the kinetic energy of the student on the bicycle, we use the formula:

Kinetic Energy = 1/2 * mass * velocity^2

Substituting the given values:
Mass = 56 kg
Velocity = 11 m/s

Kinetic Energy = 1/2 * 56 kg * (11 m/s)^2
Kinetic Energy = 1/2 * 56 kg * 121 m^2/s^2
Kinetic Energy = 3,388 J.

Therefore, the correct answer is 3,388 J.
