  1. Unit 1 – Test Review

  2. Position (meters) Write the mathematical expression for Object 1 90 Position = -2(m/sec)*time + 90(m) 45 tIme(sec)

  3. Position (meters) Predict the position at 100 seconds. 90 Position = -2(m/sec)*time + 90m 45 time (sec) x = - 110 meters

  4. What is the same at the point where the objects intersect. The position A B

  5. Are the velocities constant? Yes, it is a straight line. A B

  6. Draw a motion map for each object on the same line. A B

  7. Position (meters) What is the velocity at 17 seconds? 40 15 20 30 45 time (sec) -8 m/sec

  8. Position (meters) What is the velocity at 40 seconds? 40 15 20 30 45 time (sec) 2.6 m/sec

  9. Position (meters) What is the total distance travelled? 40 15 20 30 45 time (sec) 80 m

  10. Position (meters) What is the total displacement? 40 15 20 30 45 time (sec) 0 m

  11. Position (meters) Make a motion map. 40 15 20 30 45 time (sec)

  12. x Look at the motion map below and make a position vs time graph t
