Josh opens a soda can by pulling on the tab. The picture shows Josh opening the soda can.

15cm/5cm
The tab is a simple machine. What is the mechanical advantage of the tab?
MA = output/input

a
.7
b
3.0
c
9.0
d
21.0

The mechanical advantage (MA) of the tab can be calculated by dividing the output distance by the input distance. In this case, the output distance is the distance the tab moves when opening the soda can (15cm), and the input distance is the distance Josh pulls on the tab (5cm).

Therefore, the mechanical advantage (MA) of the tab is:

MA = output/input
MA = 15cm/5cm
MA = 3.0

So, the correct option is b) 3.0.
