Problem

A shell is fired from a cannon with a velocity

v

(m/sec.) at an angle

\theta

with the horizontal direction. 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. Find the speed (in m/sec.) of the other piece immediately after the explosion. a.

3v \cos \theta

2v \cos \theta

\frac{3}{2}v \cos \theta

\sqrt{\frac{3}{2}}v \cos \theta
