ECZ 2016 · O-Level Paper 1 — Travel Graphs
A particle accelerates uniformly from a speed of v m/sto a speed of 5v m/sin 20 seconds. Find an expression, in terms of v, for the acceleration.
- A. 4v m/s²
- B. v⁄4 m/s²
- C. 5v m/s²
- D. v⁄5 m/s²
Verified working — step 1
Acceleration = change in speed ÷ time = (5v − v)⁄20 = 4v⁄20 = …The full step-by-step working and final answer are included with Premium — checked against ECZ marking standards.
