0A particle moves along the parabolic path \( y=a x^{2} \) in such a way that the \( x \) component of the velocity
\( \mathrm{P} \)
remains constant, say \( c \). The acceleration of the particle is
(1) \( a c \hat{k} \)
(2) \( 2 a c^{2} \hat{j} \)
(3) \( a c^{2} \hat{j} \)
(4) \( a^{2} c \hat{j} \)
