A worker sets up a pulley 12 meters high,
to move a box with a rope of length 28 meters. If the
worker moves to the left at 1
2 meter per second, then
at what rate does the box move along the ground
when the worker is 5 meters from point A ?
Thanks in advance for any help. Btw, as a hint, it's a triangle problem, there's a diagram, but it won't copy/paste properly.
s/n kk, got the diagram attached, thanks again =]
