A body moving with uniform acceleration has two points(5, 15) and (20, 60) on the velocity-times graph of its motion. Calculate
- A. 0.25ms-2
- B. 3.00ms-2
- C. 4.00ms-2
- D. 9.00ms-2
Correct Answer: B. 3.00ms-2
Explanation
slope = acceleration
a = \(\frac{v_2 - v_1}{t_2 - t_1} = \frac{60- 15}{20 - 5}\)
= 3ms-2
