Solution
Deceleration in the region B = +Slope of v.t. graph from B to C
= `"BG"/"GC"=(14-6)/(16-12)=8/4` = 2 ms−2

State whether true or false. If false, correct the statement.
Acceleration can get negative value also.
Assertion: The accelerated motion of an object may be due to change in magnitude of velocity or direction or both of them.
Reason: Acceleration can be produced only by change in magnitude of the velocity. It does not depend the direction.
It is possible to have objects moving with uniform speed but variable acceleration.
