In physics lab, Piper attaches a wireless sensor to one of the spokes of a bicycle wheel spinning freely on its axle. The graph below shows the sensor's height above the ground, in centimeters, over time t, measured in seconds.
What is the midline?
Time (in seconds)
Sensor's height (in cm)
Time (in seconds)
Sensor's height (in cm)
(2.5, 73)
(6.5, 73)
(4.5, 25)
(0.5, 25)
1 answer
The midline is the horizontal line in the middle of the graph, representing the average height of the sensor above the ground. In this case, the midline would be at a height of 49 cm.
