Physics Exercises/Forces

  1. Suppose you are in a moving train. Assume it is moving with a constant acceleration. You have just come from the mall, and have with you only a ball of string, a long ruler, and a massive paperweight. Describe how to find the acceleration of the train using these items. Assuming that the train accelerates at 3 m/s2, what would you measure?
