A cannon fires a projectile with a speed of 110 m/s at a 30° to the horizontal. The opening of the cannon's muzzle is 1.2 m above the ground, and the rifling inside the canon causes the canon ball to rotate about an axis with angular velocity = 81 s¹. The mass of the cannon ball is m = 7.0 kg, and it's radius is r = 0.04 m. The moment of inertia is I = 4.5 x 10-³ kg m². What is the total mechanical energy of the canon ball as soon as it leaves the muzzle?
