Relation between Kinetic Energy and Linear Momentum
If a body has a mass of $ \displaystyle m$ then, $ \displaystyle \begin{array}{l}\text{K}\text{.E}\text{.}=\dfrac{1}{2}m{{v}^{2}}=\dfrac{1}{{2m}}{{m}^{2}}{{v}^{2}}\\\Rightarrow \text{K}\text{.E}\text{.}=\dfrac{{{{p}^{2}}}}{{2m}}\end{array}$ where $ \displaystyle p$ is
