A particle’s motion is represented by the velocity-time graph. The displacement of the particle is taken to be zero at $t = 0$. Point Q marks a point on its path. Which row in the table is correct?
- Atimes for maximum displacement: $2.5\,\text{s}$; acceleration at point Q $= 2\,\text{m s}^{-2}$
- Btimes for maximum displacement: $5\,\text{s}$; acceleration at point Q $= 2\,\text{m s}^{-2}$
- Ctimes for maximum displacement: $2.5\,\text{s}$; acceleration at point Q $= 0$
- Dtimes for maximum displacement: $5\,\text{s}$; acceleration at point Q $= 0$
