Unit 1 – Test Review

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

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

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

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

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

7
What is the velocity at 17 seconds? -8 m/sec time (sec) Position (meters)

8
What is the velocity at 40 seconds? 2.6 m/sec time (sec) Position (meters)
