a marble that is rolling across a lab table has a velocity of 0.7m/s. If the table is 0.9m high, how far from the edge of the table will the ball travel in the horizontel direction before it hits the floor ?

find time of fall:
h= 1/2 g t^2 solve for t.
then distance= horizontal velocity*timeinair 
i don't get it
