1. The problem statement, all variables and given/known data A ball is thrown with initial velocity 20m/sec against a wall 50 meters away. It is released from a height of 1.8 meters, and hits the wall at 1.2 meters. Find the angle of the throw. 2. Relevant equations 50=20t*cos(theta) -.6=20t*sin(theta)-.5(9.8)(t^2) 3. The attempt at a solution Is it possible to solve this problem without knowing t(time between launch and hitting the wall)? Thanks for the help, I need to know if I'm missing a formula or something.
