The shock absorbers on a car are broken, so the 1560-kg car body oscillates freely atop the four identical springs attached to the axel. Each spring has spring constant 1.30 x 105 N/m. Four people of identical mas simultaneously get into the car. This causes the car to oscillate vertically with a period of 0.370s. Determine the mass of each passenger. Assume that the combined total mass of the car and passengers is distributed evenly over the springs. (Hint: look at how each mass is supported by the single spring.)
Thanks for your help, it is greatly appreciated!
