Figure given here shows the variation of velocity of a particle with time.

Find the following:
(i) Displacement during the time intervals.
(a) 0 to 2 sec., (b) 2 to 4 sec. and (c) 4 to 7 sec
(ii) Accelerations at
(a)t = 1 sec, (b) t = 3 sec. and (c)t = 6 sec.
(iii) Average acceleration
(a) between t = 0 to t = 4 sec.
(b) between t = 0 to t = 7 sec.
(iv) Average velocity during the motion.

Explanation

(i)displacement =Area enclosed between
v-t graph and time axis.
(ii) Acceleration = slope of v-t curve
(iii) Average acceleration=`"Total change in velocity"/"Total time"`
(iv) Average velocity =`"Total displacement "/"Total time "`
