Vadim throws a boomerang into the air with a velocity of 25 m/s at an angle of 40.0 with respect to the horizontal. It has a mass of 0.50 kg and is rotating at 5 rev/s. The moment of inertia of the boomerang is given as I = 1/12 (mI'2 ) where I = 0.80 m. What is the total energy of the boomerang when it leaves the hand
