A shell is projected from a level ground with a velocity u at angle θ to the horizontal. When the shell is at the highest point it explodes into two equal fragments. One of the fragments retraces its path to the point of projection. At what distance from the point of projection does the other fragment fall.

Question

A shell is projected from a level ground with a  velocity u at angle θ      to the horizontal. When the  shell is at the highest point it explodes into two equal fragments. One of  the fragments retraces its path to the point of projection. At what distance  from the point of projection does the other fragment fall.
