1 Name:_________________________________________ Physics 4A FIRST EXAM Chapters 1 - 4 Fall 1993 Solve the following problems in the space provided. Use the back of the pages if needed. Each problem is worth 20 points. You must show your work in a logical fashion. At the very least you must state the names of physical principles that you use. You may use the information on the last page. Your score will be maximized if your work is easy to follow because partial credit will be awarded. 1. Many objects do not undergo constant acceleration and therefore the kinematic equations do not apply. If you happen to know the acceleration as a function of time for such an object, describe how you would go about finding the velocity at any time and the position at any time. Besides the acceleration as a function of time, there are two additional pieces of information you would need. What are they?
