For two cars A and B in motion distance time graph is shown:

(a) State initial positions of car A and car B.
(b) When and at what distance from the origin, these two cars would meet?
(c) Find final speed of car A and car B.

Explanation

(i) The initial position of car A = Origin .O.
The initial positon of car B is 500 m from origin .O.
(ii) At 40 s and 600 m away from .O.
(ii)` 15 ms ^(-1), 2.5 ms ^(-1)`
