The distance travelled by an object in time ttt is given by s=(2.5)t2s=(2.5) t^{2}s=(2.5)t2. The instantaneous speed of the object at t=5 s\mathrm{t}=5 \mathrm{~s}t=5 s will be:
  1. A
    5 ms−15 \mathrm{~ms}^{-1}5 ms−1
  2. B
    12.5 ms−112.5 \mathrm{~ms}^{-1}12.5 ms−1
  3. C
    62.5 ms−162.5 \mathrm{~ms}^{-1}62.5 ms−1
