2026 PCSS P1 Q24

The diagram below shows the speed-time graph of a bus journey.

The bus accelerated from rest at \(1.5\text{ m/s}^2\) to a speed of \(v\text{ m/s}\) in 20 seconds, and travelled at this speed until \(T\) seconds before it came to a stop at 80 seconds.

The total distance travelled for the whole journey was 1650 m.

1. Find the value of
   1. \(v\),[1]
   2. \(T\).[2]
2. Describe the motion of the bus between 20 seconds and \(T\) seconds.[1]
