1.Sheldon and Leonard are building a brick wall of science. They uses a wheelbarrow that carries bricks that weigh 600N. They uses 120N to lift the bricks. What is the mechanical advantage of the wheelbarrow?
2. Rachel, Emma, and the wheelchair have a total weight of 700 N. Ross needs a force of 140 N to push them up the ramp of the hospital. What is the mechanical advantage of the ramp?
3.To pull a weed out of a garden, you can apply a force of 50 N to the shovel. The shovel applies a force of 600 N to the weed. What is the mechanical advantage of the shovel?
4.Barney and Ted are nailing a nail into the wall. Ted moves the handle of the hammer 10 cm and the nail moved 2.5 cm. What is the ideal mechanical advantage of their hammer?
