    Answer

    U Max velocity= Potential energy= kinetic energy

    The potential energy is the product of mass * acceleration due to gravity * height

    The kinetic energy is the product of 1/2 mass* square of velocity.

    Max Velocity=mgh= 1/2mv^2

    Mass is given as 62kg, height =1.2m and g= 9.8m/s^2

    62kg* 9.8m/s^2*1.2= 1/2*62kg* v^2

    729.12=31v^2

    V^2= 729.12/31 =23.52

    V^2=square root of 23.52

    V= 4.85m/s
