Question

the formulas used to analyze the horizontal and vertical motion of projectiles launched at an angle involve the use of which function(s)? tangent only cosine only sine and tangent cosine and sine

Explanation:

When analyzing the horizontal and vertical motion of projectiles launched at an angle, the initial velocity is resolved into components. The horizontal - component of the initial velocity is $v_{0x}=v_0\cos\theta$ and the vertical - component is $v_{0y}=v_0\sin\theta$, where $v_0$ is the initial velocity and $\theta$ is the launch angle. So, cosine and sine functions are used.

Answer:

D. cosine and sine
