    So the mechanic uses the mechanical lift to lift the car that weighs 11000N to the height h=2.5 meters. We want to calculate the amount of work needed to lift the car. So the formula for work is W=F*h or work is equal to force multiplyed by the distance (height). So now we can plug in the numbers and we get W=10000N*2.5m=27500J so the correct answer is B.
