Question 2.4 A kayaker paddles in a straight line at a speed of 1m/s for four seconds, <strong>and</strong><br />
then at a speed of 3m/s for one second. What is the average speed for the five second interval?<br />
Question 2.5 On the graph below, the positive direction represents north <strong>and</strong> the negative<br />
direction is south. The solid curve shows the motion of cart A. A second cart B starts from<br />
an initial position which is two meters farther to the south. The velocity of cart B is twice the<br />
velocity of cart A. Draw the position versus time for cart B on the same graph.<br />
