Samantha and Emily are pushing a box of textbooks in the same direction across their classroom. Samantha is applying a force of 10 newtons, and Emily is applying a force of 10 newtons. What is the net force of their efforts?

20N

Explanation:

Force applied by Samantha = 10N

Force applied by Emily = 10N

Since both Samantha pushes the box of textbook in the same direction; their forces are additive.

Net force applied on box = Force applied by Samantha + Emily

Force is a pull or push on a body

Net force = 10N + 10N = 20N
