Next scroll down to “Projectile At Angle”. This menu option will do step by step analysis of the projectile given initial values such as Angle, Initial Velocity and Initial height.
Here is an example:
Now, if you are to find Initial Speed, Launch Angle etc just scroll further down in the menu as we have those scenarios covered too.
