Cutnell and Johnson, Chapter 1 through section 1.3; Chapter 2.\
Reviewing these problems gives you good exposure to this week's main topics, in practice. Conceptual MCAT problems and solutions are posted in the Review problems section of our webpage. Quantitative problems are from the end-of chapter problems (not questions) in your textbook. They are worked in the Student Solutions Manual [SSM]; solutions are also posted in the review section of our website ( |http://www.cc.emory.edu/PHYSICS/Faculty/Benson/141/review.html| ), for those without this text.

Use the following to answer questions 1--7:A robot used to deliver parts along an assembly line is programmed so that the time at each station is minimized and correlated with the work being done on the line. Its motion has been modelled assuming constant accelerations over different time intervals. A portion of the modelling over an eight second interval is shown in the graph below.
- What is the robot's speed at t= 1.5 seconds?
-
- The robot is at rest at
- 4.5 s
- 1.5 s
- 6.5 s
- 7 s
- What is the robot's average acceleration between t= 4 and t = 7 seconds?
-
- What is the robot's acceleration at t = 7 seconds?
-
- How much distance does the robot cover between t=2 and t=4 seconds?
-
- How far from its position at t=0 seconds will the robot be after t=8 seconds?
-
- What is the robot's average velocity between t= 0 and t=8 seconds?
-
- What is the robot's speed at t= 1.5 seconds?

- Quantitative II:
-
Complete these end-of-chapter problems (not questions!) from your textbook. For these, you are expected to fully write up your solution. Summarize what information and variables are given in the problem statement, then state what equations and approach can be used to find the answer requested. Provide any needed justification if the equation or approach is not universally valid. Derive the answer formally, being sure all your equalities have sensible left and right hand sides. Plug in numbers only in your last step. Show derivation of your units. Box your final answer, which should be in the form variable = number units (direction if needed), for a quantitative question.
