In a different planet, the acceleration ...

In a different planet, the acceleration due to gravity is `2m//s^(2)`. A particle is thrown horizontally at a speed of `3 m//s` from a height of `10 m`. The equation of trajectory of the particle comes out to be `x^(2)=alphay`. Find the value of `alpha` [Take `+X-`axis alonf the direction of projection and `+Y` axis towards the surface of planet.]
