Ashell is fired from the ground with the initial speed of 1570 m/s at an initial angle of 41 to the horizontal.
neglecting air resistance, find the shell's horizontal range.

Explanation:

The horizontal range of a projectile is given by

where

u is the initial speed

is the angle of launch

g = 9.8 m/s^2 is the acceleration of gravity

For the shell in this problem,

u = 1570 m/s

Substituting into the equation, we find the range of the shell:
