You are working for the Highway Department. In mountainous regions, highways sometimes include a runaway truck ramp, and you are asked to help with the design of such a ramp. A runaway truck ramp is often a lane of gravel adjacent to a long downhill section of roadway where trucks with failing brakes may need assistance to stop.

Question
You are working for the Highway Department. In mountainous regions, highways sometimes include a runaway truck ramp,
and you are asked to help with the design of such a ramp. A runaway truck ramp is often a lane of gravel adjacent to a long
downhill section of roadway where trucks with failing brakes may need assistance to stop. Working with your supervisor, you
develop a worst-case scenario: a truck with a mass of 4.50 x 104 kg enters a runaway truck lane traveling at 31.1 m/s.
Assume that the maximum constant value for safe acceleration of the truck is -5.00 m/s². Any higher magnitude of
acceleration increases the likelihood that semi-trailer rigs could jackknife. Your supervisor asks you to advise her on the
required length (in m) of a runaway truck lane on a flat section of ground next to the roadway.
