Please make sure that you do the following during the midterm:
Each problem is worth 20 points. We will give partial credit on this midterm , so if you are not altogether sure how to do a problem, or if you do not have time to complete a problem, be sure to write down as much information as you can on the problem. This includes any or all of the following: Drawing a clear diagram of the problem, telling us how you would do the problem if you had the time, telling us why you believe (in terms of physics) the answer you got to a problem is incorrect, and telling us how you would mathematically solve an equation or set of equations once the physics is given and the equations have been derived. Don’t get too bogged down in the mathematics; we are looking to see how much physics you know, not how well you can solve math problems.
If at any point in the exam you have any questions, just raise your hand, and we will see if we are able to answer them.
Copy and fill in the following information on the front of your bluebook:

a. Where, , and when, , was the ball thrown in Tom's frame? b. Where, , and when, , was the ball thrown in Harry's frame? (If you cannot get part a, you can express your answer in terms of and/or for partial credit.) c. How long did it take the ball to travel from Dick to Tom in Harry's frame? (If you cannot get part a, you can express your answer in terms of and/or for partial credit.)
