F'(x) = 5sin(x) + 5x*cos(x) = 0.

Then, setting f'(x) = 0 gives: 
5sin(x) + 5x*cos(x) = 0 ==> tan(x) + x = 0. 

Then, use Newton's Method to solve tan(x) + x = 0 on 0 <= x <= π. This solves to get x ≈ 2.028758. Using the Second Derivative Test, you can show that this gives a maximum. Therefore, the required maximum value is: 
f(2.028758) = 2(2.028758)sin(2.028758) ≈ 3.639411........google told me this

What prohibits you from increasing your speed until the vehicle that is passing you has completed the passing maneuver?

Answer

Well, it should be common courtesy

Explanation

Common courtesy is the politeness that people are usually expected to show in situations that require common sense. In this case, you do not require Florida Law officers to enforce it. As a driver, maintaining a constant speed until a vehicle that is passing you has completed the passing maneuvers is practicing road safety and courtesy.
