WHo ever is genious solve this (challenge for you) W tnch part ot graph shows motion
with uniform (a) velocity (b) acceleration
(c) retardation ?
(iv) (a) Is the magnitude of acceleration higher
or lower than that of retardation ? Give a
reason. (b) Compare the magnitude of
acceleration and retardation.
Ans. (i) By finding the area enclosed by the graph
in that part with the time axis (ii) 2 : 1
(iii) (a) BC (b) AB (c) CD (iv) (a) lower, as
slope of line AB is less than that of the
10. The velocityâ€”tirne graph of a moving body is
given below in Fig. 2.43.
