1. The problem statement, all variables and given/known data 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!
