## Centre of mass formula list with solved examples and problems

This article contains a list of the center of mass formulas along with some center of mass problems and examples. Center of mass formula list For a system of N particles,the position vector of center of mass is $\vec{R}_{CM}=\frac{m_1\vec{r}_1+m_2\vec{r}_2+………..+m_N\vec{r}_N}{m_1+m_2+…..+m_N}=\frac{\sum_{i=1}^N{m_i\vec{r}_i}}{M}$ The…

## The maximum range of projectile formula

Let us consider a projectile projected with initial velocity $$v_{0}$$ making an angle $$\theta_0$$ with the horizontal as shown below in the figure. We know that the horizontal range of a projectile is the distance traveled by the projectile during…
