Get help if you have trouble answering these questions. An “attempt” is not enough. On the due date or before, you will show this to me and keep it. I will give you credit and the right to take the mastery test. You will then look at the solutions in a notebook -not online. These problems do not need to go into your bound solutions book with your classwork and homework problems. You are allowed to work with anyone else you wish to work with. Working with a friend who did well on the test is a GREAT IDEA. 1. What is the instantaneous velocity at 2.5 min? 2. Which single minute time interval show a positive displacement? 3.
