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

Answer

Brief Explanations:

When analyzing the horizontal and vertical motion of projectiles launched at an angle, we break the initial velocity vector into its 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, sine and cosine functions are used.

Answer:

D. cosine and sine
