    Answer:

    K = 5706.6 J

    Explanation:

    Given that,

    The mass of a bullet, m = 50 g = 0.05 kg

    The velocity of the bullet, v = 720 km/hr = 477.77 m/s

    We need to find the kinetic energy of the bullet​. The kinetic energy of an object is due to its motion. It can be given by the formula as follows :

    K=\dfrac{1}{2}mv^2\\\\=\dfrac{1}{2}\times 0.05\times 477.77 ^2\\\\K=5706.6\ J

    So, the required kinetic energy of the bullet is equal to 5706.6 J.
