# Solve: Projectile in Motion

A projectile of mass 20.2 kg is fired at an angle of 65.0 degrees above the horizontal and with a speed of 84.0 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? Take the free fall acceleration to be g = 9.80 m/s^2.

b) How much energy is released during the explosion? Take the free fall acceleration to be g = 9.80 m/s^2.
