The initial kinetic energy imparted to a 0.1 kg bullet is 1036 J. The acceleration of gravity is 9.81 m/s2 . Neglecting air resistance, find the range of this projectile when it is fired at an angle such that the range equals the maximum height attained.
Answer in units of km.

First find the launch angle. See
http://www.jiskha.com/display.cgi?id=1298683188
for that.
Equations for range and maximum height can be found there.
Range does not depend upon mass.
