A cannot shoots a shell at an initial velocity v 1  of 25 m/s, at an angle of 60° with respect to the horizontal. At the top of the trajectory, the projectile explodes into two fragments: one of m/3 and another of mass 2m/3. One fragment (2m/3), whose speed immediately after the explosion is zero, falls vertically. a) How far from the gun does the other fragment (m/3) land, assuming that the terrain is level and that the air drag is negligible? b) How far from the gun the center of mass of the shell falls? c) Calculate the final velocity of the center mass (vector quantity) at the time when the m/3 fragment hits the ground

Question

A cannot shoots a shell at an initial velocity v 1  of 25 m/s, at an angle of 60° with respect to
the horizontal. At the top of the trajectory, the projectile explodes into two fragments: one
of m/3 and another of mass 2m/3. One fragment (2m/3), whose speed immediately after
the explosion is zero, falls vertically.
a) How far from the gun does the other fragment (m/3) land, assuming that the terrain
is level and that the air drag is negligible?
b) How far from the gun the center of mass of the shell falls?
c) Calculate the final velocity of the center mass (vector quantity) at the time when the
m/3 fragment hits the ground.
