A shell is fired from a cannon with a speed ‘v’ at an angle θ with the horizontal direction as shown in the figure. At the highest point in its path, it explodes into two pieces of equal mass. One of the pieces retraces its path to the cannon. The speed of other piece immediately after the explosion is

\(\sqrt{\frac{3}{2}}\)v cos⁡θ
