A bicycle racer named Orlando sprints at the end of a race to try to clinch a victory. When Orlando is $300$ meters from the finish line, he has speed of $11\mathrm{.}5\frac{m}{s}$ and starts his sprint. He accelerates at a rate of $0\mathrm{.}500\frac{m}{s^2}$ for $7\mathrm{.}00s,$ then maintains this maximum speed for the rest of the race.

$($a$)$ Draw a kinematic diagram along the $x$ axis for Orlando from the moment he starts his sprint until he reaches the finish line. Because there are three important positions in this final portion of the race there should be three labeled points along the $x$ axis. At each of the three points, assign a variable name to Orlando's position, velocity, and time. Assign a value for the acceleration between points. Since there are three important points you may want to use subscripts $1,2,$ and $3,$ for the three locations, instead of i for initial, and $f$ for final. If you know the value of a variable, write that down. If not put a question mark by the variable.
