Question

Rosa uses the formula (vi cos)t to do a calculation. Which value is Rosa most likely trying to find? A)the vertical acceleration of a projectile launched at an angle B)the vertical acceleration of a projectile launched horizontally C)the horizontal displacement of a projectile launched at an angle D)the horizontal displacement of a projectile launched horizontally

Answer 1

I think the answer is d if we throw in horizontal

Answer 2

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

-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.
