    Given that an object with a mass of 54kg travels at 15m/s^2, determine the kinetic energy of the object.

    KE = 0.5 x mv^2

    M (mass) = 54kg

    V (velocity) = 15m/s^2

    Then, we plug the values in.

    KE = 0.5 x 54 (15^2)

    Now, we solve.

    KE = 0.5 x 54 (225)

    KE = 0.5 x 12150

    KE = 6075

    Now, that we have solved the formula, we can see that the kinetic energy of the object is 6,075J.

    Thus, the kinetic energy of the object is 6,075J.
