Bob fires a cannon horizontally off a 125 meter cliff.the cannonball leaves the cannon traveling at 144 meters per second. How far from the cliff will the cannonball land?

Answer 1

h = 0.5*t^2 = 125 m.
4.9t^2 = 125
t^2 = 25.51
Tf = 5.05 s. = Fall time.

Dx = Xo * Tf = 144m/s * 5.05s = 727 m.
From the cliff.
