There a box of 25N 25N 50 N and 100 N 1.Explain how you calculate the net force in any direction on the box.
2.Suppose an upward force of 15 N is added to the box, What will the net vertical force be on the box?.
3.What force could be applied to the box to make the net force in the horizontal direction zero? explain.
4.Suppose a force of 25 N to the right is added to the box. What will be the net force to the right?
pls help my grade is dropping ​
