Homework Statement
Two cars, A and B, move along the x-axis. Figure 2.39 is a graph of the positions of A and B versus time. (a) In motion diagrams (like Fig 2.13b and Fig 2.14b), show the position, velocity, and acceleration of each of the two cars at t=0, t=1s, and t=3s. (b) At what time(s) if any, do A and B have the same position? (c) Graph velocity versus time for both A and B. (d) At what time(s), if any, do A and B have the same velocity? (e) AT what time(s) if any, does car A pass car B? (f) At what time(s), if any does car B pass car A?

Part B: At t=1s and 3s.
Part C: http://www.freeimagehosting.net/t/4m23n.jpg
Part D : I think at 1<x<3. Somewhere between there. Possibly at 2 seconds I think.
Part E: at 3 seconds car a passes car b.
Part F: After one second car b passes car a until they meet again at 3 seconds. Then car a passes car b.
Is this correct? Thanks in advance!
