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

It may possibly be c i think |-/

    5.5 n======    assuming that      we have      m = 0.145 kg    a = 38 m/s²therefore    5.51 n, but two significant figures.final answer: 5.5 n
