Problem

A particle moves along the parabolic path

x=y^2+2y+2

in such a way that the

y

-component of its velocity remains

5\ \text{m s}^{-1}

during the motion. The magnitude of the acceleration of the particle is: (1)

50\ \text{m s}^{-2}

(2)

100\ \text{m s}^{-2}

(3)

10\sqrt{2}\ \text{m s}^{-2}

(4)

0.1\ \text{m s}^{-2}
