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

Explanation

i)Displacement during the time intervals.
a) 0 to 2 sec. b) 2 to 4 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.
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")`
i)a) 8m b)15m c)12m
iia) `4ma^(-2)` b)0 c) `-8//3ms^(-2)`
iii)a) `2m//s^(2)` b)0 iv) `(36)/(7)m^(-1)`
