#### Measure the x-value of the racer at each dot. List your data in a table similar to Table 1.1, showing each position and the time at which it occurred. Make a position-versus-time graph for the drag racer. Because you have data only at certain instants, your graph should consist of dots that are not connected together.

#### Your roommate drops a tennis ball from a third-story balcony. It hits the sidewalk and bounces as high as the second story. Draw a complete motion diagram of the tennis ball from the time it is released until it reaches the maximum height on its bounce. Be sure to determine and show the acceleration at the lowest point.

#### Figure Ex1.11 shows two dots of a motion diagram and vector $\displaystyle \vec{v_2}$$\displaystyle \vec{v_2}$. Copy this figure and add vector $\displaystyle \vec{v_1}$$\displaystyle \vec{v_1}$ and dot 1 if the acceleration vector $\displaystyle \vec{a}$$\displaystyle \vec{a}$ at dot 2 (a) points to the right and (b) points to the left.
