A particle moves uniformly with speed v along the path y=kx^2 .Taking k as a positive constant, acceleration of the particle at x=0 is _________?

2. Relevant equations

options-a)2kv^2 b)kv^2 c)1/2(kv^2) d)2kv

3. The attempt at a solution

I did- y=kx^2

differentiating we get,

v= 2kx

again differentiating we get,

a=2k

so there'es an uniform acceleration of a=2k at all points.

but none of the options match!
