    Answer:

    Kinetic energy, K = 14.97 J

    Explanation:

    We have,

    Mass of the object, m = 5.2 kg

    Velocity of the object, v = 2.4 m/s

    It is required to find the kinetic energy of the object. As it is moving with some velocity, it will have kinetic energy. It is given by :

    K=\dfrac{1}{2}mv^2\\\\K=\dfrac{1}{2}\times 5.2\times (2.4)^2\\\\K=14.97\ J

    So, the kinetic energy of the object is 14.97 J.
