1. The problem statement, all variables and given/known data Given your assigned projectile launcher determine the muzzle velocity. angle of launcher = 45degrees distance to bottom of barrel = 25.6 cm distance traveled when fired = 119.2cm Ignore Air resistance 2. Relevant equations I don't know where to start since I have an angle. 3. The attempt at a solution I don't know where to begin since the projectile is basically starting from a platform at an angle.
