Homework Statement
A ball is thrown horizontally from the top of a cliff with an initial Vo(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.
Homework Equations
The Attempt at a Solution
components: Vx=Voxcosθ Vy=Voysinθ
then i plugged the x component to find t:Vx=x/t... t=x/(Voxcosθ)
next i plugged t into a y position function Y=Yo+Voyt+1/2at^2
0=h+(Voysinθ )(x/Voxcosθ)+(1/2*-9.8*(x/Voxcosθ)^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?
