Given alongside is the velocity-time graph for a moving body:

Find:(i) Velocity of the body at point C.
(ii) Acceleration acting on the body between A and B.
(iii) Acceleration acting on the body between B and C.

"\n

(i). Velocity of the body at point C is $40\ km/h$.

(ii). Acceleration acting on the body between A and B $=\frac{change\ in\ speed\ from\ A\ to\ B}{time-period}$

$=\frac{40-20}{3-0}$

$=\frac{20}{3}$

$=6.66\ km/h^2$

(iii). Acceleration acting on the body between B and C $=\frac{change\ in\ speed\ from\ B\ to\ C}{time-period}$

$=\frac{40-40}{6-3}$

$=0$
