Question

A shell is fired from a canon with a velocity $\mathrm{Vms}^{-1}$ at an angle $	heta$ with the horizontal. At the highest point in its path, it explodes into two pieces of equal mass. One of the piece retraces its path back to the canon. The speed of the other piece immediately after explosion in $\mathrm{ms}^{-1}$ is\
