EXPERIENCE COLLEGE BEFORE COLLEGE Mechanics, Heat, and Sound (PHY 302K) Name: Explain here: The ball is speeding up at a constant rate dependent upon the slope at the ramp. The velocity at the top of the ramp will be zero. The line will have a positive slope because the detector is at the top of the ramp, therefore, the ball is moving away from the detector. Part VI For each graph below, write a description of how one or more people would have to move in front of the motion detector to create the graph shown with the motion detector set to show velocity vs. time. You may need to test out the first few before going on to predictions on the more difficult remaining graphs. Some may not be possible with one person, some may be just impossible. If you feel that this is true in any case, explain why. After writing your descriptions, try to reach a consensus within your group and then test your predictions. Each member of the group should try to create every graph. Description: Description: Description: Constant positive velocity Speeding up at a constant Slowing down at a over time rate in the positive constant rate to zero then direction speeding up at the same constant rate in a positive direction Confrey, Algebra by Design, 1997.
