A cyclist is initially at rest at the origin. At t=0 she starts to accelerate at a constant rate, along a straight road reaching a velocity of 2.60 m/s after 12.0 seconds. 12.0 seconds after starting a prairie dog runs across her path and the cyclist hits the brakes, producing a new constant acceleration. 13.0 seconds after starting, the cyclist has a velocity of 1.50 m/s .

C. What is her average acceleration in this 13-s interval?

D. What is the position of the cyclist at 13s, x13 ,?

Express your answer using 3 significant figures.
