The diagram above is a velocity- time graph of a moving object. Calculate the distance travelled when the acceleration is zero.
300 m
90 m
150 m
210 m
Correct answer is C
The acceleration is between the times 3 secs and 8 secs.
Distance = \(velocity \times time\)
= \(30 \times (8 - 3) = 30 \times 5\)
= \(150 m\)
