    Answer:

    Mass, m = 2650 kg

    Explanation:

    We have,

    Kinetic energy of  Mr. Thomson’s prius is 641300 J

    He is moving with a velocity of 22 m/s

    It is required to find the mass of Mr. Thomson’s prius.

    Kinetic energy,

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

    Plugging all the values, we get :

    m=\dfrac{2K}{v^2}\\\\m=\dfrac{2\times 641300}{(22)^2}\\\\m=2650\ kg

    So, the mass of Mr. Thomson’s prius is 2650 kg.
