    Answer:3m/s

    Explanation:

    mass (m) = 50kg

    Kinetic energy = 225 joules

    Kinetic energy = (m x (velocity) ^2) / 2

    225 = (50 x (velocity) ^2) / 2

    Cross multiplying we get

    225x2=50x (velocity) ^2

    450=50x (velocity) ^2

    Divide both sides by 50

    450/50 = (50x (velocity) ^2) / 50

    9 = (velocity) ^2

    Taking the square root of both sides we get

    √9=velocity

    3=velocity

    Velocity=3m/s
