Special sections of roadway are sometimes paved with "rumble strips" to alert inattentive drivers. In a particular case the grooves are spaced L = 0.26 m apart and the depth of each groove is d = 1.3 cm. As you drive over this rumble strip, the tires of your car oscillate about their equilibrium positions with a frequency of f = 60.5 Hz. What is the vertical position, in cm, at t=1.79s? With your tire oscillating at f=60.5Hz and the distance between the grooves L=0.26m, what is the speed of your car in km/h?
