ECZ 2019 · GCE Paper 1 — Travel Graphs
The speed-time graph shows an object which starts from rest and accelerates uniformly for 2 seconds to 10 m/s, moves at that speed for 6 seconds, accelerates to V m/sover the next 5 seconds, then retards for 8 seconds to a halt. Calculate the acceleration during the first 2 seconds.
- A. 10 m/s²
- B. 2 m/s²
- C. 5 m/s²
- D. 20 m/s²
