    607.5 m/s

    Step-by-step explanation:

    K. E. = 1/2 m v^2

    mass = kg

    m = 15

    velocity = m/s

    v = 9

    now substitute the variables

    1/2 (15) (9) ^2

    first square the 9

    (9) ^2 = 9 times 9 = 81

    1/2 (15) (81)

    now multiply 15 and 81

    15 times 81 = 1215

    1/2 (1215)

    now divided 1215 by 2

    1215/2 = 607.5 m/s
