Acceleration — Unit test Answers

The diagram shows a motion map.

Which is an example of speed?

Study the velocity vs. time graph shown.

Suppose the initial position of an object is zero, the starting velocity is 3 m/s and the final velocity was 10 m/s. The object moves with constant acceleration. Which part of a velocity vs. time graph can be used to calculate the displacement of the object?

The chart shows data for a moving object.
