You are pushing on a heavy door, trying to slide it open. If your friend stands behind you and helps you push, how have the forces changed?
a. The net force applied will increase.
b. The net force will decrease.
c. There will be less friction.
d. The applied force does not change

Answer 1

Answer:

A. The net force applied will increase

Explanation:

This is an example of Newton's second law that says that you will need more force to move an object of a lot of mass. F = m×a;  F=Force= M= Mass×A= Acceleration

Answer 2

A. The net force applied will increase.

This is an example of Newton's second law that says that you will need more force to move an object of a lot of mass. F = m×a;  F=Force= M= Mass×A= Acceleration
