The horizontal distance that the cannonball will travel is 383.33m

In order to find the horizontal distance, we will use the formula for calculating the range expressed as:

$R = u\sqrt{\frac{2H}{g} }$ where:

u is the velocity

H is the height

g is the acceleration due to gravity

$R = 120\sqrt{\frac{2(50)}{9.8} }\\R = 120\sqrt{\frac{100}{9.8} } \\R=120\times 3.1943\\R=383.33m$

Hence the horizontal distance that the cannonball will travel is 383.33m
