Question 833051: I'm trying to help my son, but we are not understanding the question very well. It's a motion diagram where he is supposed to plot the velocity vs. time, and the acceleration vs. time. He has more than one of these to complete, and we are not understanding.

Thank you in advance.

Label the points A to D left to right (A is (0,0))
----------------
The speed is the slope
From A to B it moves -3 in 2 seconds --> -3/2 units/second
From B to C --> 7/3
From C to D --> zero
----------------------
Acceleration = 0 except at the points where it changes direction
Not clear what's needed there.
