Prediction: In this laboratory, you will be applying a constant force (using a constant hanging mass) to a system. For this an air cart will be placed on a level air track with a string attached to it over a pulley. A hanging mass will then be hung from the end of the string. Predict what the position, velocity and acceleration (versus time) graphs will look like if the frictionless air cart is given a small push toward the motion detector (away from the hanging mass). The air cart will first move toward, then away, from the motion detector due to the string tension
