A 32.0 kg cart is at rest on a frictionless, horizontal surface. The cart experiences an unbalanced force, causing the cart to accelerate at a rate of +5 m/s2.
A student claims that the normal force acting on the cart is equal in magnitude to the weight of the cart. Is the student correct?
A
Yes, the student is correct because the normal force is the equal and opposite reaction to the cart’s weight being applied on a surface, as described in Newton’s Third Law of Motion.
B
Yes, the student is correct because the normal force is directly proportional to the mass of the cart, as described in Newton’s Second Law of Motion.
C
No, the student is incorrect because the normal force is not the equal and opposite reaction to the cart’s weight being applied on a surface, as described in Newton’s Third Law of Motion.
D
No, the student is incorrect because the normal force is inversely proportional to the mass of the cart, as described in Newton’s Second Law of Motion.
