rosa uses the formula $(v_{i}cos\theta)delta t$ to do a calculation. which value is rosa most likely trying to find?\n the vertical acceleration of a projectile launched at an angle\n the vertical acceleration of a projectile launched horizontally\n the horizontal displacement of a projectile launched at an angle\n the horizontal displacement of a projectile launched horizontally

Answer

Explanation:

Step1: Recall projectile - motion formulas

The horizontal component of the initial velocity of a projectile launched at an angle $\theta$ with initial velocity $v_i$ is $v_{ix}=v_i\cos\theta$.

Step2: Recall the displacement formula

The displacement formula is $d = v\times t$. In the horizontal direction, the horizontal displacement $x$ of a projectile is given by $x = v_{ix}t=(v_i\cos\theta)t$, where $\Delta t$ is the time - of - flight. When a projectile is launched horizontally, $\theta = 0^{\circ}$ and $\cos\theta = 1$, and the formula still holds. When launched at an angle, the horizontal component of velocity is used in the displacement formula.

Answer:

the horizontal displacement of a projectile launched at an angle
