The speed-time graph of a particle moving along a fixed direction is shown in Fig. Obtain the distance traversed by the particle between
(a) t = 0 s to 10 s. (b) t = 2 s to 6 s.
What is the average speed of the particle over the intervals in (a) and (b)?

Distance travelled will be the area under the speed time curve. (a) Distance travelled is: 2 x 1/2 (5x12) = 60m (b) Slope of upward increasing curve: 12/5 and of decreasing curve it is: -12/5 This gives the rate of change of speed with time. Thus equation of line, speed at 2nd second...

Distance travelled will be the area under the speed time curve.
 
(a) Distance travelled is: 2 x 1/2 (5x12) = 60m
 
(b) Slope of upward increasing curve: 12/5 and of decreasing curve it is: -12/5
      This gives the rate of change of speed with time.
      Thus equation of line, speed at 2nd second will be:12/5*2 = 4.8 m/s
      Speed at 6th second: 12 - 12/5*1 = 48/5 = 9.6 m/s....  (because rate of change is negative
      and from 12 to 0)
      Thus total distance travelled = 1/2(12-4.8)(5-2) + 1/2(12-9.3)(6-5) = 12.15 m
