The 450-kg trailer is pulled with a constant speed over the bumpy road, which may be approximated by a cosine curve having an amplitude of 50 mm and a wave length of 4 m. If the trailer is supported by two springs each of 400 N/m stiffiness. Determine the speed v which will cause the greatest vibration (resonance) of the trailer. Neglect the weight of the wheels.
