P1-4

The figure shows the motorcyclist velocity versus time as he accelerates from rest on a city street. The segments from 0-3 and 6-8 are straight lines. The curve from 3-6 is parabolic with the start point and end point shown and maximum somewhere in between. The curve from 8-10 is parabolic with a starting slope equal to that from 6-8 and an ending slope of zero. The curve from 10 to 11.deltadeltadeltadelta is parabolic with horizontal slope at (10,10) and reaching point (11.deltadeltadeltadelta,0).

Sketch the s-t and a-t curves and determine the total distance travelled in 11.deltadeltadeltadelta seconds.
