Question

Rosa uses the formula (vi cos)t to do a calculation. Which value is Rosa most likely trying to find?

Answer 1

Answer;

C - the horizontal displacement of a projectile launched at an angle

Explanation;

-The horizontal displacement of a projectile is only influenced by the speed at which it moves horizontally (vix) and the amount of time (t) that it has been moving horizontally.

-The range (or horizontal displacement) will increase as the angle is increased from 0 degrees to 45 degrees. The maximum range occurs at 45 degrees. As the angle is further increased to values greater than 45 degrees, the horizontal displacement decreases.

Answer 2

The best and most correct answer among the choices provided by the question is the horizontal component acceleration of a projectile launched at an angle
