If an input force of 202 n is applied to the handles of the wheelbarrow with a mechanical advantage of 2.2. how large is the output force that just lifts the load

For this case, the relationship between the two forces is given by:

Where,

Then, replacing the values we have:

Having the calculations we have:

the output force that only lifts the load is:

the answer is y = 11.54

hope this : )

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
