Question 2 Multiple Choice Worth 4 points)
(01.03 MC)
A golf ball is at rest on the grass when a golfer walks up and applies 10 N of force to it. There is 2 N of friction, resulting in 8 N of net force. What will happen to the ball?
O It will remain at rest.
It will move in the direction opposite the net force.



Answer :

To determine what will happen to the golf ball, we need to understand the forces acting on it and the resultant motion. Let's go through it step-by-step:

1. Applied Force: The golfer applies a force of 10 Newtons (N) to the golf ball. This force is directed towards moving the ball.

2. Friction Force: There is a frictional force of 2 Newtons (N) opposing the motion of the ball. Friction always acts in the direction opposite to the applied force.

3. Net Force Calculation: The net force acting on the golf ball is calculated by subtracting the frictional force from the applied force:

[tex]\[ \text{Net Force} = \text{Applied Force} - \text{Friction Force} = 10 \, \text{N} - 2 \, \text{N} = 8 \, \text{N} \][/tex]

4. Direction of Net Force: Since the applied force is greater than the frictional force, there is a net force of 8 Newtons acting in the direction of the applied force (the same direction the golfer pushed).

5. Effect on the Golf Ball: According to Newton's Second Law of Motion, an object will accelerate in the direction of the net force acting on it. Since the net force of 8 Newtons is acting in the direction the golfer applied the force, the golf ball will move in that direction.

Therefore, the correct answer is:
- The golf ball will move in the direction of the applied force, which, in this context of the question, reaffirms that the correct interpretation is that the ball moves as a result of the net force acting on it.

Given the choices:
- It will remain at rest.
- It will move in the direction opposite the net force.

The correct choice is neither directly listed, implying the basic understanding that it moves in the direction of the net force. Since none perfectly match the precise language, we adapt:
Correct answer aligned with common sense and inferred choice:
- The ball will move in the direction of the applied force.
