Question

Thomas needs to move an 80 kg rock, but cannot lift it. He decides to use a

lever to move it and applies 200N of force to the rock. What is the MA of
the lever? (you may use 'io for the value of gravity when solving for this
problem...don't forget resistance force is equal to weight or mass times
gravity) *

Answer 1

4

Step-by-step explanation:

The weight of the rock is W = mg = (80 kg) (10 m/s²) = 800 N.

The mechanical advantage is therefore 800 N / 200 N = 4.
