While driving behind a car traveling at 3.45 m/s, you notice that one of the car's tires has a small hemispherical bump on its rim as shown in the following figure. (a) Explain why the bump, from your viewpoint behind the car, executes simple harmonic motion. This answer has not been graded yet. (b) If the radii of the car's tires are 0.380 m, what is the bump's period of oscillation (in s)? s (c) What If? You hang a spring with spring constant k = 100 N/m from the rear view mirror of your car. What is the mass (in kg ) that needs to be hung from this spring to produce simple harmonic motion with the same period as the bump on the tire? kg (d) What would be the maximum speed of the hanging mass in your car (in m/s) if you initially pulled the mass down 8.00 cm beyond equilibrium before releasing it? (Enter the vertical component of the speed only.) m/s
