a cannon ball is shot from a 100 m high cliff with an inital velocity of 24m/s and at an angle of 32 degrees. what is the overall final velocity of the cannonball?

WEll,the kinetic energy of the ball at the end must equal the initial KE added to the initialpe
1/2 m vf^2=1/2 m vi^2+mg*100
solve for Vf
