Answer:
160 ft
Explanation:
As the canon ball was shot horizontally, its initial vertical velocity is 0. The ball vertical motion is generated by the gravitational acceleration g = 32m/s2. We can calculate the time it takes for it to drop 64 ft
This is also the time it takes to travel horizontally at a constant rate of 80 ft/s if we ignore air resistance.
So the ball would land 160ft away from the wall on the ground
