Final answer:
The net force is 15 N.
Step-by-step explanation:
In this scenario, you and your friend are exerting forces in opposite directions. The force you apply is 25 N and your friend applies a force of 10 N in the opposite direction. To find the net force, we need to subtract the smaller force from the larger force.
Net Force = |25 N - 10 N| = 15 N.
So, the net force is 15 N.
