🤓 Based on our data, we think this question is relevant for Professor Chow's class at UCF.
A 20.0-kg projectile is fired at an angle of 60.0° above the horizontal with a speed of 80.0 m/s. At the highest point of its trajectory, the projectile explodes into two fragments with equal mass, one of which falls vertically with zero initial speed. You can ignore air resistance.
(a) How far from the point of firing does the other fragment strike if the terrain is level?
(b) How much energy is released during the explosion?
