CSEC Physics · May/June 2007 · Paper 2 · Question 2(b)(ii)

A car moves from A towards C with a constant velocity of 30 m s⁻¹. The driver sees an obstruction at C as the car passes A. Due to reaction time, the car travels 27 m at the same velocity to B before brakes are applied. The car then decelerates uniformly to a halt at C, which is 54 m from B.

The car takes 3.6 s to travel from B to C. In the space below, draw a velocity-time graph to represent the motion of the car between A and C.

This question uses a figure or table from the paper — you'll see it when you practise.
