Highway Speeding#

../../../../../_images/L7Q1.png

A police radar located at O serves automated tickets to speeding highway drivers. It is located \(d = {{params.d}}ft\) from the highway. As a car cruises by, \(\theta\_{1} = {{params.angle1}}^{\circ}\) and the radius from the radar is increasing at \(\dot r = {{params.r_dot}}ft/sec\). The angle \(\theta\_{2} = {{params.angle2}}^{\circ}\)

Part 1#

Determine the corresponding speed \(v\) of the car.

Answer Section#

Please enter in a numeric value in \(ft/s\).

Part 2#

Determine the value of \(\dot \theta\).

Answer Section#

Please enter in a numeric value in \(rad/s\).
