MA = 2.00 meters / 0.50 meters = 4
Therefore, Anne is incorrect. The mechanical advantage of the ramp is 4, not 0.25. Mechanical advantage is the ratio of the output force to the input force, or the ratio of the distance traveled by the output force to the distance traveled by the input force. In this case, it represents the effort force needed to lift an object up the ramp compared to the weight of the object.
Anne says that the mechanical advantage of a 2.00 meter ramp that is 0.50 meters high is 0.25. Is she correct? Why or why not? (show work!)
MA=length of ramp/height of ramp
