Homework Statement
I need to find two ways to calculate initial velocities (2 versions) of an object just clearing over a 9.99 m wall.
Homework Equations
kinematics equations
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?
