A small trailer and its load have a total mass \( \mathrm{m} \). The trailer can be modeled as a spring with constant \( k \). It is pulled over a road, the surface of which can be approximated by a sine curve with an amplitude of \( 40 \mathrm{~mm} \) and a wavelength of \( 5 \mathrm{~m} \). Maximum vibration amplitude occur at \( 35 \mathrm{~km} / \mathrm{hr} \). What happens if the driver speeds up to 50 \( \mathrm{km} / \mathrm{hr} ? \)
