1. The problem statement, all variables and given/known data I need to find two ways to calculate initial velocities (2 versions) of an object just clearing over a 9.99 m wall. 2. Relevant equations kinematics equations 3. The attempt at a solution Way 1 I was trying is to say dx = 40m , dy = 10m, ay= -9.81m/s^2. The thing is, I can't get started even for y because I'm missing too many variables, namely viy, vfy, and t. The second way is to say the angle is 45 degrees, so viy is (something)sin45 and vx is (something)cos45. But again, I'm missing too many variables to calculate it. Am I missing something?
