Question

a student tested a variety of interacting forces to determine how they would result in motion of an object. if the student used the forces as shown in the lettered choices above, predict which results would occur. select all that apply. a the variable shown by letter b would result in a movement of the object to the left. b the variable shown by letter b would result in a movement of the object to the right. c the variable shown by letter a would result in a movement of the object to the right. d the variable shown by letter c would result in a movement of the object to the right. e the variable shown by letter d would result in a movement of the object to the right.

Explanation:

Step1: Analyze forces in A

In A, two equal - magnitude forces act to the right. Net force is to the right, so object moves right.

Step2: Analyze forces in B

In B, two equal - magnitude forces act in opposite directions. Net force is zero, object doesn't move.

Step3: Analyze forces in C

In C, a larger force acts to the right and a smaller force acts to the left. Net force is to the right, object moves right.

Step4: Analyze forces in D

In D, two equal - magnitude forces act in opposite directions. Net force is zero, object doesn't move.

Answer:

C. The variable shown by letter A would result in a movement of the object to the right.
D. The variable shown by letter C would result in a movement of the object to the right.
