(a)

To determine

The kinetic energy of $\text{K}$ meson in the given decay process.

(b)

To determine

The reason for which the decay $\varphi \to {\text{K}}^{+}+{\text{K}}^{-}+{\pi }^0$ is not been observed.

(c)

To determine

The reasons for which the decays $\varphi \to {\text{K}}^{+}+{\pi }^{-}$ and $\varphi \to {\text{K}}^{+}+{\mu }^{-}$ are not been observed.
