lead runner, but since he is not allowed to leave his current location he must rotate the
camera to keep the runner in frame. At the instant shown in Figure 3.23 , θ = 50◦, the
runner has a speed of 6.00 m/s and an acceleration of 0.10 m/s2 to the left. What are
the values of ̇θ (theta dot) and ̈θ (theta double dot) at this instant? Look at the attached picture for additional information
