An unstretched spring is slowly from street level to the top of a tall building. Compared to street level,
the spring has more _______________________________________.
Suppose you drop the spring from the top of the building and it toward the street below. Neglecting
non conservative forces, such as air resistance, the kinetic energy of the spring at the instant just before
it hits the street is ________________________________________.
If air resistance is not neglected in the previous question, the kinetic energy of the spring at the instant just
before it hits the street is ________________________________________. - ✔✔gravitational
energy at the top of the building
about equal to its gravitation potential energy at the top of the building
greater than its gravitational potential energy at the top of the building.

You are pushing a file cabinet across a floor in a straight line at a constant speed. Which of the
following can you correctly conclude about the forces acting on the file cabinet?
A, If you were to exert twice as much force on the file cabinet, it would slide across the floor at twice its
original speed.
B. The force that you are exerting on the file cabinet is greater than the force that friction is exerting on
it.
