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

im guessing the west of station b

russian is not my first language, so i'm afraid i can't write out an answer in russian, but hopefully you can find a way to do so. here's my best translation of the problem: you're given a plot of a particle's position in one-dimensional space over time, and you're asked to find either the total distance traveled by the particle after 6 seconds had elapsed, or the total displacement of the particle after 6 seconds.

if you want the total distance traveled, you would first need to determine the particle's velocity as a function of time, then integrate that over the 6-second interval. we know the position function is quadratic with roots at 0 and 6, so we have

where is unknown. because the position is parabolic, there is symmetry about the midpoint at , and we know that

so that the position function is

which means the velocity is

then the total distance traveled is

so the total distance traveled is 20 m.

on the other hand, if you want to find displacement: the particle starts at and ends at , so its displacement is 0.
