An automobile can be considered to be mounted on four identical springs as far as vertical oscillations are concerned. The springsof a certain car are adjusted so that the oscillations have afrequency of 2.62 Hz. (a) What is the spring constant of each spring if the mass of the car is 1910 kgand the mass is evenly distributed over the springs? (b) What will be the oscillation frequency (in Hz) if five passengers, averaging 80.8 kg each, ride in the car with an even distribution of mass?
