The formula to calculate the kinetic energy is:

Kinetic Energy (KE) = 1/2 x mass (m) x velocity^2 (v^2)

Given that the mass of the vehicle is 700 kg and the velocity is 6 m/s, we can substitute these values into the formula:

KE = 1/2 x 700 kg x (6 m/s)^2

Simplifying the equation:

KE = 1/2 x 700 kg x 36 m^2/s^2
KE = 18,900 kg*m^2/s^2

The unit for kinetic energy is Joules (J), so we have to convert the unit:

1 kg*m^2/s^2 = 1 J

Therefore, the kinetic energy of the 700-kg vehicle traveling at a speed of 6 m/s is 18,900 J.

Answer: 18,900 J
