Question

Gardeners would need to use 960 N of Potted tree 45 cm onto a deck instead they set up a lever if they press the lever down 2 m how much force do they use to lift the tree?
216N
1920N
21,600N
432N

Answer 1

The force required is equivalent to the weight of the tree. Since the weight of the tree is 960 N, the force needed to lift the tree using a lever with a mechanical advantage of 2 is 480 N.

Therefore, the correct answer is not listed. The correct answer is 480N.
