Work is defined as the product of force acting on an object that moves with a certain displacement.

The formula for work is, W = fd.

We don't have any force yet so,

W = fd
W = mad

In this case, we have these three already so we can already solve the work. (I'll use the GRESA format).

G: m = 60 kg; d = 10 m; a (due to gravity) = 9.8 [tex]m^{2} [/tex]

R: Work

E: W = fd

S: W = fd
    W = mad
    W = (60)(9.8)(10)
        = (588)(10)
        = 5880
        *The least significant figure on the given is 1 so we should only have 1 SF.

A: 6000 J
work=forcexdistance travelled along the direction of force.  f=massx accelaration due to gravity.  mass=60kg a=10m/s2  w=fxdist=mxgx h=60x10x10=6000joules
