A shell traveling with velocity $\mathbf{v}_{\mathrm{o}}$ explodes into three pieces of equal masses. Just after the explosion, one piece has velocity $\mathbf{v}_{1}=\mathbf{v}_{\mathrm{o}}$ and the other two have velocities $\mathbf{v}_{2}$ and $\mathbf{v}_{3}$ that are equal in magnitude $\left(v_{2}=v_{3}\right)$ but mutually perpendicular. Find $\mathbf{v}_{2}$ and $\mathbf{v}_{3}$ and sketch the three velocities.
A shell is fired from a cannon with a velocity $v$ at an angle $\theta$ with the horizontal direction. At the highest point in its path, it explodes into two pieces, one retraces its path to the cannon and the speed of the other pieces immediately after the explo- sion is : (a) $3 v \cos \theta$ (b) $2 v \cos \theta$ (c) $\left(\frac{3}{2}\right) v \cos \theta$ (d) $\frac{\sqrt{3}}{2} v \cos \theta$
