The eastbound car in the example is driven by an off-duty police officer, who knows her speed was exactly 30.0 m/s. From studying the angle (and the mass of the two vehicles), she concluded that the truck was over the speed limit of 70 km/h driving on that secondary road. Of course, the truck also failed to stop before entering the main road. If the truck were not speeding, what should be the maximum angle for (in degrees counterclockwise from the +x-axis) in this accident?

≤ ______ ° counterclockwise from the +x-axis (If I could just get guidance, not the final answer, please.)
