LaToya uses 50 newtons (N) of force to pull a 500 N cart. Which statements are correct about calculating LaToya's mechanical advantage? Select the two that apply.
a
The mechanical advantage is 100.
b
The output force is 50 N.
c
The input force is 50 N.
d
The output force is 450 N.
e
The input force is 500 N.
f
The mechanical advantage is 10.
The correct statements are:
b. The output force is 50 N.
c. The input force is 50 N.
Mechanical advantage is calculated by dividing the output force by the input force. In this case, the output force is the force used to pull the cart (50 N) and the input force is the weight of the cart (500 N). Therefore, mechanical advantage is 50/500 = 0.1 or 1/10, which can be represented as a ratio of 1:10. So, statement f is also correct. However, statement a and d are incorrect as they do not reflect the actual mechanical advantage calculation. Statement e is incorrect as it refers to the weight of the cart, not the input force.
