This is the best that I could come up with to help...:

to calculate for work: 
w= force x distance 
w = mass x gravity x distance 
w= mass x acceleration x distance 

to calculate for power: 
p=work / time 
p= mass x gravity x distance / time 
p = mass x acceleration x distance / time

Work: force times displacement. W = Fd 
Power: work over time. P = W/t
