Answer the following questions about this velocity-time graph of a crazed power walker. A=1, B=2, C=4, D=8, E=16, F=32, Cannot-be-determined=64. Add together the values of points which satisfy the condition stated and enter on CPS.

1. At which points is the walker's velocity decreasing?

2. At which points is the magnitude of the acceleration the greatest?

3. At which points is the acceleration zero?

4. At which points is the walker moving in the +x direction?

5. At which points is the walker's position negative?

Sketch a position-time graph of this velocity-time graph.
