1. The problem statement, all variables and given/known data If I know a launched objects initial velocity and angle of launch, how would I find a specific x value given a certain y value? 2. Relevant equations 3. The attempt at a solution I tried setting the equation y=Vo*sin(angle)*t-.5gt^2 to equal the y value given which is 45. Then I should be able to solve for t and plug that into the x equation for kinematics which is x=Vo*cos(angle)*t in turn finding the desired x value. The equation as result isn't even solvable in my case so I'm confused as to why it doesn't work.
