Alyssa applies a force to a box of books, accelerating it across a desk at 2 m/s2. Another student adds more books to the box,
doubling its mass. If Alyssa applies the same amount of force to
the box again, what will the new acceleration be?
O 2 m/s2
O 0.1 m/s2
O 4 m/s2
O 1 m/s2

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?
