Finding a re-arrangement of the equation

 exp(x)−3x−1=0

which will converge to a solution in the interval (1,3) to four decimal places when the fixed point iteration method is used.

2.      (10 points)

The design of a car suspension system involves a trade-off between comfort and stability for all driving conditions and speeds.  Vibration analysis based on proper modeling of a car and required performance upon hitting a pothole reached the following equation:

cos

⎛⎜⎜⎝0.05 mk − 4cm²₂ ⎞⎠⎟⎟+ 4kmc−c2 sin⎝⎛⎜⎜0.05 mk − 4cm²2 ⎟⎟⎠⎞= 0

where the mass of the car m = 1.2 × 10³ kg and the damping coefficient of its shock system is c = 1 × 10⁴ kg/s.  Find an appropriate value of k that satisfies this condition.
