Answer:
C
Explanation:
To calculate adjacent of triangle use

where 45 is the hypotenuse, and a is the adjacent side (horizontal component)

then round to 38.2
Since your constantly changing the height of the cup (your independent variable) then this causes the distance it travels to change (your dependent variable) so it’s basically because the slope is changing as well.
<span>First, a problem would be the sheer amount of wind resistance. If an object travels as far as even just one hundred miles it could encounter different wind patterns that could change the trajectory of the object. Second would be the size of the projectile. This creates a problem because the bigger it is, the more momentum it could potentially pick up, given that it is not too big to complete the distance. This is another problem with size, how far the projectile can actually travel. You would have to actually calculate the ideal size of said object to make sure it could actually make the distance you're looking for. hope it helps:)</span>
