    Answer:

    Technician B

    Explanation:

    The kinetic energy of an object is possessed when it is in motion. It is given by :

    K=\dfrac{1}{2}mv^2

    m is mass, v is speed

    The kinetic energy is directly proportional to its speed. It does not depend on its weight. It would mean that Technician B is correct as he says that “the kinetic energy of a moving vehicle is directly proportional to its speed”.
