sarah was attempting to pull the cart seen here through point a in the diagram. she could not do it. her sister suggested
setting up a pulley system to sarah with the task. the girls added the pulleys and ropes you see here. how did this pulley
system sarah move the cart?
the force required to move the cart is 100 n/8 or 12.5 n.
the force required to move the cart is cut in half or 50 n.
the force required to move the cart is divided by three or 33.33 n.
the force required to move the cart is multiple by the distance and then
