Use the worked example above to you solve this problem. a 1.27 x10^3 kg car is constructed on a frame supported by four springs. each spring has a spring constant of 2.03 x10^4 n/m. if two people riding in the car have a combined mass of 1.60 x10^2 kg, find the frequency of vibration of the car when it is driven over a pothole in the road. find also the period and the angular frequency. assume the weight is evenly distributed.
