1. The problem statement, all variables and given/known data So, our lab entails the students launching a projectile at a certain angle into a cup at a certain distance away. The launcher is 37 cm off of the ground and the cup is 7cm of the ground, so the Dy = 37-7 = 30cm. We will be given the angle in class and will be asked to position the cup at a certain distance. Lets say for example it is 35 degrees. How could we solve for Dx with only two variables. Any thoughts? Thanks. 2. Relevant equations tanθ = Vy/Vx 3. The attempt at a solution I was thinking of using Vx = Vy/tanθ and then possibly substituting something in for Vy from another kinematic equation but that would require time and we are only given measuring tape, no timer.
