ECZ 2016 · O-Level Paper 1 — Travel Graphs
The diagram below is the speed-time graph of a particle. The particle accelerates uniformly from a speed of v m/s to a speed of 5v m/s in 20 seconds. Find an expression in terms of v, for acceleration.
- A. 4v m/s2
- B. v⁄4 m/s²
- C. 5v m/s2
- D. v⁄5 m/s²
Verified working — step 1
Acceleration is the gradient of the speed-time graph - the same rule works with letters as with numbers.The full step-by-step working and final answer are included with Premium — checked against ECZ marking standards.
