A ball is projected vertically upward with an initial velocity of $\displaystyle 50 \mathrm{~ms}^{-1}$ at $\displaystyle t=0 \mathrm{~s}$. At $\displaystyle t=2 \mathrm{~s}$, another ball is projected vertically upward with same velocity. At $\displaystyle t=$ \_\_\_\_ s , second ball will meet the first ball $\displaystyle \left(\mathrm{g}=10 \mathrm{~ms}^{-2}\right)$.
