Problem

A particle starts from the origin of coordinates at time

t = 0

and moves in the

xy

-plane with a constant acceleration

\alpha

in the

y

-direction. Its equation of motion is

y = \beta x^2

. Its velocity component in the

x

-direction is (1) variable (2)

\sqrt{\frac{2\alpha}{\beta}}

(3)

\frac{\alpha}{2\beta}

(4)

\sqrt{\frac{\alpha}{2\beta}}
