Projectile at two instants of time

A projectile thrown from ground moves at an angle of 30 degrees with the horizontal after 2 second of its flight and moves horizontally after further 1 second.

Calculate the initial velocity of the Projectile.

Note: Enter the answer as the $$\left \lfloor v \right \rfloor$$ where v is the answer to the problem Take $$g = 10m/s^2$$
