A car starts from rest and accelerates at $\displaystyle 5 \mathrm{~m} / \mathrm{s}^2$. At $\displaystyle \mathrm{t}=4 \mathrm{~s}$, a ball is dropped out of a window by a person sitting in the car. What is the velocity and acceleration of the ball at $\displaystyle \mathrm{t}=6 \mathrm{~s}$ ? (Take $\displaystyle \mathrm{g}=10 \mathrm{~m} / \mathrm{s}^2$ )
