Question

A body accelerate at 6m/s square calculate the distance travelled in third second?

Answer 1

the answer is 15m

Answer 2

after 2 s , the velocity is ... 2 * 6 m/s^2 = 12 m/s

after 3 s , the velocity is ... 3 * 6 m/s^2 = 18 m/s

the average velocity during the 3rd second is ... (12 m/s + 18 m/s) / 2
