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 = 0.15 cm. As you drive over this rumble strip, the tires of your car oscillate about their equilibrium positions with a frequency of f = 67 Hz
Enter an expression that describes the vertical position, y(t), of one of the car tires as a function of time, t, in terms of the defined quantities. Assume the motion is sinusoidal, with its argument in radians and the positive y-axis up. Take the tire’s equilibrium position as y = 0 and take y(0) = 0 and increasing.
Find the vertical position of the tire, in centimeters, at the time t = 1.1 s.
With your tire oscillating at a frequency of f = 67 Hz and the distance between grooves L = 0.26 m, what is the speed of your car, in kilometers per hour?
When four people with a combined mass of 280 kg sit down in a car, they find that the car drops 1.00 cm lower on its springs. Then they get out of the car and bounce it up and down. What is the frequency of the car's vibration if its mass (when it is empty) is 2.0 ✕ 103 kg?Hz

The object is pulled down, thereby stretching the spring, and then released. The object oscillates up and down, and the time T required for one complete up-and-down oscillation is given by the equation T = 27 Vmlk, where k is known as the spring constant. What must be the dimension of k for this equation to be dimensionally correct?arrow_forwardA 0.23 kg mass is suspended on a spring which stretches a distance of 5.3 cm. The mass is then pulled down an additional distance of 11 cm and released. What is the displacement from the equilibrium position with the mass attached (in cm) after 0.33 s? Take up to be positive and use g = 9.81 m/s2. The initial condition should be set as y(0)=-A because the mass is pulled below the equilibrium (the origin along y-axis) and released. Hint: Get k from the displacement as it was done in this example. The equation will have ω = (k/m)1/2, and the phase will be such that it will be a cosine with a negative amplitude, because it starts at a negative displacement.arrow_forward
