1. The problem statement, all variables and given/known data Okay so, a rock is throw from an initial height, ho, at a speed, vo, and an angle [theta] from the horizontal. Find the rocks velocity as a function of time. 2. Relevant equations Vxo=(Vo)(cos[theta]) Vyo=(Vo)(sin[theta]) Acceleration is constant. 3. The attempt at a solution Well I know that V(t)=Vo+at But since the rock is thrown from an angle I got confused. Do I have to replace the Vo with the two equations for the x and y component of velocity? Since I can solve for Vo, but then it is equal to two different things. Thanks!
