Consider a spring that does not obey hooke's law very faithfully. one end of the spring is fixed. to keep the spring stretched or compressed an amount x, a force along the x-axis with x-component fx=kx−bx2+cx3 must be applied to the free end. here k=100n/m, b=700n/m2, and c=12000n/m3. note that x> 0 when the spring is stretched and x< 0 when it is compressed.

An engineer designs a roller coaster so that a car travels horizontally for 152 ft, then climbs 137 ft at an angle of 34.0° above the horizontal. it then moves 137 ft at an angle of 48.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)
