A student is trying to move an object by pushing it. When the student applies 20 Newtons of force to the object, it does not move. When the student applies 40 Newtons of force to the object, it moves. Which of the following identifies the greatest amount of force the object could be applying to the student?

• 20 Newtons

• 30 Newtons

• 40 Newtons

• 50 Newtons

A student wanted to get an object to move with a net force of (up)15 Newtons. The combinations of forces that can be exerted to create that net force are:

• (up) 13 Newtons + (right) 2 Newtons

• (down) 35 Newtons + (up) 20 Newtons

• (up) 7 Newtons + (up) 8 Newtons

• (up) 15 Newtons + (down) 15 Newtons
