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. m

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.

For t 0, an object of mass m experiences no force and moves in the positive x direction with a constant speed vi. Beginning at t = 0, when the object passes position x = 0, it experiences a net resistive force proportional to the square of its speed: Fnet=mkv2i, where k is a constant. The speed of the object after t = 0 is given by v = vi/(1 + kvit). (a) Find the position x of the object as a function of time. (b) Find the objects velocity as a function of position.
