Expert Answer:
1. From the graph it is clear that OB' > O'A'.
Thus, A lives closer to the college.
2. The position- time graph of A starts from the origin (t = 6 : 30 ) and B starts from 6 : 34.
This indicates that A started earlier than B. Here, on X-axis 1 unit = 1 min.
Hence, the A started earlier than B by a time interval of OC = 4 min.
3. The speed is represented by the steepnes (slope) of the graph. The position-graph of B is steeper than the position-time graph of A.
Thus, we can conclude that B is faster than A.
4. The time interval of B is less than that of A. That is, OE > OD. This indicates that B reaches earlier at 6 : 42.
5. They cross each other at point K.

- Starting from rest, an object is uniformly accelerated to a speed of 60m/s in 20s. The object travels with this speed for next 40s and is then brought to rest by a uniform retardation in the next 30s.Sketch velocity time graph and calculate the acceleration, retardation and the total distance travelled. Hint: acceleration =rate of change of velocity. distance covered =area under velocity-time graph .
