Question

An orange of mass m falls into a wagon. Assume the orange experiences upward acceleration magnitude ‘a’ when it comes in contact with the wagon. What is the correct expression for the normal force magnitude Fn exerted on the orange? Consider upward as the positive direction.


F=m/(a+g)
F=m*(a-g)
F=(a+g)/m
F=m*(a+g)

Answer 1

Answer:

Explanation:

The weight of an object equals the mass of the object multiplied by the acceleration of gravity. Multiply the two values together. In order to find the normal force, you need to multiply the weight of the object by the cosine of the angle of incline.

Answer 2

Answer: F=m(a+g)

Explanation:
