Question

1. A ski lift travels up a mountain at a steady rate of 83 feet per minute. Then all of a sudden it stops and sitsfor a while. Finally, it begins to ascend up the mountain to the top.a) Name the independent and dependent variables.b) Sketch a graph to represent the situation. Remember to label each axis.

Answer 1

The independent and dependent variables in this situation are the time and the velocity respectively because the velocity change depending on the time.

So, a graph that represents the situation is:

Because first, A ski lift travel at a constant rate of 83 (green line), then it stops and sits for a while (red line) and finally, it ascends up to the top.
