A cannon is fired horizontally from atop a 40.0 m tower. The cannonball travels 175 m horizontally before it strikes the ground. With what velocity did the ball leave the muzzle?

How long does it take to fall 40 m?
h=1/2 g t^2
solve for t.
then, velocity= 175/time

Hi
Actually g is 9.8 if it were to be acceleration then it would be 9.8

yo
9.80
