To determine the resulting motion of the block, we need to analyze the net force acting on it.
The student applies a force of 10 newtons to the right, while the force of friction exerts a resistive force of 5 newtons to the left.
Calculating the net force:
Net force = Applied force - Frictional force
Net force = 10 N (to the right) - 5 N (to the left)
Net force = 5 N (to the right)
Since there is a net force of 5 newtons acting to the right, the block will accelerate in the direction of that net force.
Therefore, the best statement that describes the resulting motion of the block is:
**The block will accelerate to the right.**
