The diagram below shows the speed-time graph of a moving object. (a) Find the acceleration of the object when t = 3.
- A. 4m/s2
- B. 20m/s2
- C. 5m/s2
- D. 3m/s2
Verified working — step 1
Acceleration is the gradient of the section CONTAINING t = 3 - and this graph starts at 4 m/s, not at rest.The full step-by-step working and final answer are included with Premium — checked against ECZ marking standards.
