The length of the cannon barrel is 1.7 m and the cannon is aimed at a 38◦angle from the ground. the acceleration of gravity is 9.8 m/s^2.
if dread pirate roberts tells you he wants the ball to leave the cannon with speed v-not = 76 m/s, what mass cannon ball must you use?
answer in units of kg. what i don't understand is that it says the vnot is 76m/s when leaving the cannon. shouldn't it be vfinal, or am i misunderstanding the question?
