Using a simple machine, a student is able to lift a 500n weight by applying only 100n. what is the mechanical advantage of the simple machine? a) 0.2 b) 1 c) 5 d) 50000

The mechanical advantage of a machine is the ratio between the output force and the input force:

In our problem, the input force is 100 N, while the output force is the weight of the object the student lifts, 500 N. So, the mechanical advantage is
