A10 kg projectile is fired from a cannon at an angle of 60^ above the horizontal and with an initial velocity of 300 m/s. at the highest point of its flight, the projectile explodes into two fragments with equal mass. one of the fragments falls vertically downwards with an initial velocity of zero.
question 1: how far from the cannon does the other fragment strike the ground( assume the ground is level)?
question 2: how much energy is released during the explosion?
