An object is moving with a uniform acceleration which is parallel to its instantaneous direction of motion. The dispalcement (s)-velocity (v) graph of this object is.

Options

A.
B.
C.
D.

Answer

C

Explanation

` u=sqrt(u^(2) +2as ) or s =(v^(2) )/(2a) -(u^(2))/(2a) rArr S ` is quadratic in v, with coeff . Of ` v^(2) ` positive as
` (a gt 0) `
` rArr ` graph is parabola opening towards positive direction of S .
