Solution

Solution Steps

Step 1: Analyzing the Forces Acting on the Physics Student

To determine if the Physics student is moving, we need to analyze the forces acting on him. The diagram shows a force being applied to the student, likely by a rope or similar mechanism. The wall is exerting a force in the opposite direction to balance this applied force.

Step 2: Determining the Net Force

If the forces exerted by the wall and the applied force are equal in magnitude and opposite in direction, the net force on the student is zero. According to Newton's First Law of Motion, if the net force on an object is zero, the object will remain at rest or continue to move at a constant velocity.

Step 3: Assessing Acceleration

Acceleration occurs when there is a net force acting on an object. Since the net force on the student is zero (the forces are balanced), the student is not accelerating. If the student is initially at rest, he will remain at rest. If he is moving, he will continue to move at a constant velocity.

Final Answer

The Physics student would not be accelerating. If he is initially at rest, he will remain at rest. If he is moving, he will continue to move at a constant velocity.
