A 2.82 kilogram projectile is fired with an initial speed of 119 meter per second at an angle of 31 degree with the horizontal. At the top of its trajectory, the projectile explodes into two fragments of masses 1.02 kilogram and 1.8 kilogram. At 3.51 second after the explosion, the 1.8 kilogram fragment lands on the ground directly below the point of explosion.
a) Compute the energy released in the explosion.
