A sprinter completes a $100\,\text{m}$ race in a straight line. The table shows how his speed changes with time during the first $5.0\,\text{s}$ of the race. What is the average acceleration of the sprinter between time $2.0\,\text{s}$ and time $3.0\,\text{s}$?
- A$1.6\,\text{m s}^{-2}$
- B$1.9\,\text{m s}^{-2}$
- C$4.1\,\text{m s}^{-2}$
- D$5.7\,\text{m s}^{-2}$
