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?

Answer 1

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
