Answer 1

Heya mate
The answer is here




♢ Question
Laura pushes on the pedals of her bike with a force of 320 N. If the bike has an output force of 640 N, what is the mechanical advantage of this bike?


Answer
She pushes her bike with = 320 N of force
Output force = 640 N



Then , the Mechanical advantage of bike is = 320 +640
= 960 Newton .



hope it helps

Answer 2

Answer:

MA = F out  / F in

      = (320N/640N)

      = 0.5

The bike has a mechanical advantage of 0.5.

Explanation: Hope this helps
