Problem 2 [25 pts[ A projectile is shot from a gun at angle 90 = 60 to the flat ground with an initial velocity of V0 = 20 m/s. Once the projectile reaches its maximum height, it explodes into 2 pieces of equal mass, with the rear piece having zero horizontal velocity after the explosion (and thus vertically dropping to the ground, as shown in figure below). What will he the total travel distance d (m, round to 1 decimal place) of the other piece of projectile from the gun, assuming zero air drag
