Running Dog#

Consider the following motion diagram for a dog running down a straight path.

A displacement time graph showing the dog increasing by 2 meters from t equals 0 seconds to t equals 2 seconds. The dog is not moving from t equals 2 seconds to t equals 6 seconds. The dog decreases 2 meters from t equals 6 seconds to t equals 8 seconds. The dog decreases to negative 2 meters from t equals 8 second to t equals 10 seconds. The dog increases 2 meters from t equals 10 seconds to t equals 12 seconds.

Answer Section#

Select all the choices that apply.

Note: You will be awarded full marks only if you select all the correct choices, and none of the incorrect choices. Choosing incorrect choices as well as not choosing correct choices will result in deductions.

  • The dog is speeding up at time \(t=7\) \(s\)

  • The dog has an average velocity of \(0\) \(m/s\) between time \(t=0\) \(s\) and \(t=8\) \(s\)

  • The dog is moving at a constant velocity between \(t=2\) \(s\) and \(t=6\) \(s\)

  • The dog is moving at the same speed at time \(t=8\) \(s\) and \(t=10\) \(s\)
