CSEC Physics · May/June 2011 · Paper 2 · Question 1(d)(i)

For the next minute, the vehicle's velocity was constant, then for the final minute, the vehicle decelerated uniformly to a stop on reaching the stadium.

Continue the velocity-time graph on page 3, to show this information and use the graph to determine the total distance travelled.

The mark scheme is shown once you've answered.
