The formula to calculate kinetic energy is:
Kinetic Energy = (1/2) * mass * velocity^2
Given:
Mass = 700 kg
Velocity = 6 m/s
Substituting these values into the formula:
Kinetic Energy = (1/2) * 700 kg * (6 m/s)^2
Kinetic Energy = (1/2) * 700 kg * 36 m^2/s^2
Kinetic Energy = 18,900 kg m^2/s^2
Since 1 J = 1 kg m^2/s^2:
Kinetic Energy = 18,900 J
Therefore, the correct answer is 18,900 J.
Kinetic Energy = (1/2) * mass * velocity^2
Given:

Kinetic Energy = (1/2) * 700 kg * 36 m^2/s^2
Kinetic Energy = 18,900 kg m^2/s^2
Since 1 J = 1 kg m^2/s^2:
Kinetic Energy = 18,900 J
Therefore, the correct answer is 18,900 J.
