To determine the motion of the block, we need to analyze the forces acting on it. The student applies a force of 10 newtons to the right, while the force of friction acts as a resistive force of 5 newtons against the motion.
To find the net force acting on the block, we subtract the force of friction from the applied force:
Net force = Applied force - Friction force
Net force = 10 N - 5 N
Net force = 5 N (to the right)
Since there is a net force of 5 newtons to the right, the block will not move at a constant speed or remain at rest. Instead, it will accelerate to the right.
Thus, the correct statement is:
**The block will accelerate to the right.**
To find the net force acting on the block, we subtract the force of friction from the applied force:
Net force = Applied force - Friction force
Net force = 10 N - 5 N
Net force = 5 N (to the right)
Since there is a net force of 5 newtons to the right, the block will not move at a constant speed or remain at rest. Instead, it will accelerate to the right.
Thus, the correct statement is:
**The block will accelerate to the right.**
