Physics

A cannonball is fired horizontally from a 240 -high cliff toward a vertical building 540 away with an initial velocity of 90.0 .

When the ball will hit the building?

A) 7.00 s
B) 6.00 s
C) less than 6.00 s
D) more than 7.00 s


If it's fired horizontally, then all of the velocity component is horizontal. Thus s=v*t so
t=540/90
How far will the object fall during that time period though?
I'm supposing that all the units are compatible. There are none given so I really don't know what to make of the question?
