How would you derive an equation for finding the velocity of an 2 kg object that slides down a 30-degree frictionless ramp?

First of all ,find the net force on the block,after it find the acceleration(i.e net force/mass of the block) of the block.
the net force on the block will be mgsin30.
hence acceleration=gsin30.
apply v=u+gsin30*t....if initial velocity is zero then u=0,otherwise it has some value.
and time is also known.... then simply find V.
