Use the worked example above to you solve this problem. a 1.27 x 10° kg car is constructed on a 10 n/m. if two people frame supported by four springs. each spring has a spring constant of 1.98 x riding in the car have a combined mass of 1.60 x 102 kq, 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. f = hz s rad/s exercise i i'm stuck! getting started hints: a 42.0 kg boy jumps on a 5.40 kg pogo stick with spring constant 3650 n/m. (a) find the angular frequency. rad/s (b) find the frequency. f= hz (c) find the period of the boy's motion. t= s
