    If there is no air resistance and the body, in this case the sky diver simply falls from the helicopter then, the motion can be described as a free-falling body. The equation that would allow us to determine the speed of the body at any time, t is,

    v (t) = vo + gt

    where v (t) is the unknown velocity, vo is the initial velocity which is equal to zero and g is the acceleration due to gravity which is equal to 9.8 m/s2.

    Substituting the known values,

    v (t) = 0 + (9.8 m/s2) (12s)

    v (t) = 117.6 m/s

    Hence, the speed of the sky diver at the end of 12 second is approximately 117.6 m/s.
