A body starting from rest moves along a straight line with a constant acceleration. The variation of speed (v) with distance (s) is represented by the graph:

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
C
By equation of motion, we have
`n^(2) = u^(2) + 2as`
Where n is final velocity, u is initial velocity, a is acceleration and t is time.

Since, body starts from rest u = 0
`therefore n^(2) = 2as`
Which is general equation of parabola.
`y^(2) = 4as`, hence graph is parabolic and is symmetrical along s-axis.
