A circular racetrack has a radius of 500 m. What is the displacement of a bicyclist when she travels around the track from the north side to the south side? When she makes one complete circle around the track? Explain your reasoning.
A person travels along a
straight road as described by the v-t
graph on the right. The person starts
at x = -3 m. On the graph paper, sketch
the following and place numbers on
2.

v (m/s)
the axes.

If you don't have graph paper, you
need to carefully draw axes with a
straight edge and carefully place
numbers at the correct positions on both axes. Using a ruler to number the axes is recommended. If the
line is straight, use a straight edge to draw it. If a line is curved, make sure the curvature is clear.
a. Sketch the graph of acceleration vs. time. Show calculations.
b. Beneath the a-t graph, sketch the graph of position vs time. The horizontal axes of the two graphs
need to be aligned. Show calculations.
A student bikes to school by traveling first dn = 1.00 miles
