Select the correct answer. an object has one force acting on it. it is a 33-newton force pointing downward. to create a net force of zero on the object, which force must be applied to it? a. a 33-newton force pointing upward b. a 1-newton force pointing upward c. a 33-newton force pointing left d. a 0-newton force pointing downward e. a 1-newton force pointing right

1. explain how you calculate the net force in any direction on the box. 2. suppose an upward force of 15n is added to the box. what will be the net vertical force 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 25n to the right is added to the box. what will be the net force to the right?
