To find the answers to the following questions, you need to calculate the total mass of the "train" formed by the coupled airline baggage carts. You would then apply Newton's second law, ( F = ma ), to determine the force required to accelerate the train under different conditions. Finally, you can use the equations of motion to analyze the motion of the train under various forces and accelerations.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- An object with a mass of #14 kg# is acted on by two forces. The first is #F_1= < 2 N , 7 N># and the second is #F_2 = < -9 N, 4 N>#. What is the object's rate and direction of acceleration?
- A truck pulls boxes up an incline plane. The truck can exert a maximum force of #5,000 N#. If the plane's incline is #pi/3 # and the coefficient of friction is #2/3 #, what is the maximum mass that can be pulled up at one time?
- How does Newton's third law apply to a cannon?
- A block weighing #14 kg# is on a plane with an incline of #pi/12# and friction coefficient of #1/5#. How much force, if any, is necessary to keep the block from sliding down?
- A box with an initial speed of #9 m/s# is moving up a ramp. The ramp has a kinetic friction coefficient of #5/6 # and an incline of #(3 pi )/8 #. How far along the ramp will the box go?
