Question 98

A cyclist starts from rest.

The table shows the readings from their speedometer every 20 s.

time / s020406080speed / (m/s)03666 \begin{array}{|l|c|c|c|c|c|}\hline \text{time / s} & 0 & 20 & 40 & 60 & 80 \\\hline \text{speed / (m/s)} & 0 & 3 & 6 & 6 & 6 \\\hline\end{array} time / sspeed / (m/s)​00​203​406​606​806​​

Which row correctly describes the cyclist's motion in the first 40 s and in the last 40 s?

A

Motion during first 40 s40\text{ s}40 s: zero acceleration; Motion during last 40 s40\text{ s}40 s: constant speed

B

Motion during first 40 s40\text{ s}40 s: non-zero acceleration; Motion during last 40 s40\text{ s}40 s: at rest

C

Motion during first 40 s40\text{ s}40 s: non-zero acceleration; Motion during last 40 s40\text{ s}40 s: constant speed

D

Motion during first 40 s40\text{ s}40 s: zero acceleration; Motion during last 40 s40\text{ s}40 s: at rest
