Question

The acceleration - velocity graph of a particle moving in a straight line is shown in figure. Then the slope of the velocity- displacement graph

A. increases linearly
B. decreases linearly
C. is constant
D. increases parabolically

Answer 1

Correct Answer - C
c. Acceleration- velocity equation from the graph is
a = kv, where k is the slope of given line.
This can also be written as
`v(dv)/(ds) = kv rArr (dv)/(ds) = k`
i.e. slope of velocity - displacement graph is same as slope of
acceleration- velocity graph which is constant.
