Question

assume that you are walking away from a motion sensor that is connected to a computer which will draw a position vs. time graph for your motion. predict (sketch) the position vs. time graph for the motion at a constant velocity towards the motion sensor. attach your sketch here.

Explanation:

When moving towards a motion - sensor at a constant velocity, the position (distance from the sensor) decreases linearly with time. So, the position - vs - time graph will be a straight - line with a negative slope. The y - intercept represents the initial position (distance from the sensor at time t = 0), and as time progresses, the position value on the y - axis decreases steadily.

Answer:

The graph will be a straight line with a negative slope starting from a non - zero y - intercept (initial position) and decreasing as time (x - axis) increases.
