A ball is thrown horizontally from the top of a cliff with an initial V_{o}(at t=os). At any moment , its direction of motion makes an angle θ to the horizontal.

1)Derive a formula for θ as a function of time, t, as the ball follows a projectile's path.

2. Relevant equations

3. The attempt at a solution

components: V_{x}=V_{ox}cosθ V_{y}=V_{oy}sinθ

then i plugged the x component to find t:V_{x}=x/t.... t=x/(V_{ox}cosθ)

next i plugged t into a y position function Y=Y_{o}+V_{oy}t+1/2at^{^2}

0=h+(V_{oy}sinθ )(x/V_{ox}cosθ)+(1/2*-9.8*(x/V_{ox}cosθ)^{^2})

this be correct because if u were given all of the initial heights and velocities the only variable left to solve for would be θ, giving you your answer right?
