I know how to solve projectile problems when they are launched from an angle if I know the angle and the initial velocity, I need to know:(adsbygoogle = window.adsbygoogle || []).push({});

a. Can you use the vertical displacement (m) and the initial velocity(m/s) to find the angle?

b. How do you find the initial velocity when you know the total horizontal displacement and the total Vertical displacement and the angle at which it is launched? (i.e. a ball is launched at a 35.0 degree angle and it clears a 21.0m wall 130.0m away, what is the initial velocity at which the ball was thrown?)
