Problem

A particle moves along the parabolic path

x = y^2 + 2y + 2

in such a way that

Y

-component of velocity vector remains

5 \text{ ms}^{-1}

during the motion. The magnitude of the acceleration of the particle is a.

50 \text{ ms}^{-2}

100 \text{ ms}^{-2}

10\sqrt{2} \text{ ms}^{-2}

0.1 \text{ ms}^{-2}
