1. We will be accelerating a cart on a track by attaching a string that passes over a pulley and to which is attached a small object, a mass holder. You know intuitively that the more mass on the holder the faster the cart will accelerate. We will find how these two quantities are related. 2. Level the track to the best of your ability. Release the cart from rest. Do not allow the cart to crash at the end of the track. Describe the motion of the cart. Is it accelerating? 3. Draw a free body diagram for the cart. Using the diagram, determine the net force on the cart. 4. Now write down Newton's second law of motion for the cart. In #3 you found the net force on the cart. Substitute this into the 2nd law.
