Me with the worksheet only the part about mechanical advantage not speed ratio

Here's the formula for mechanical advantage.
It's very important, and you should memorize it:

      Mechanical Advantage  =  (output force) divided by (input force) .

#1).  Force that moves the object = output force = 550N
        Force that it takes  =  input force  =  200N
       
       Use the formula:

       (output force) divided by (input force) = 550N/200N =  2.75  . 

#2).
#3).
#4).
#5).
#6).
#7).
#8).
#9).
#10).

All of the rest of the problems on the page tell you the input force
and the output force.  They can be solved by using the same formula
to calculate the mechanical advantage, just like I did in #1).

I disagree with the first sentence of #11.  But by the time you get there,
you'll be an expert in mechanical advantage, so you can investigate and
decide who's correct ... the sheet or me.
