- A 5-kg mass is attached to a spring with stiffness 225 N/m. The damping constant for the system is 30√√5 N-sec/m. If the mass is pulled 10 cm to the right of equilibrium and given an initial rightward velocity of 3 m/sec, what is the maximum displacement from equilibrium that it will attain? The general solution is y(t) = (Do not use d, D, e, E, i, or I as arbitrary constants since these letters already have defined meanings.) The maximum displacement is meters. (Type an exact answer, using radicals as needed.)A pendulum is formed by pivoting a long thin rod about a point on the rod. In a series of experiments, the period is measured as a function of the distance d between the pivot point and the rod's center. (a) If the rod's length is L = 1.11 m and its mass is m = 26.8 g, what is the minimum period? (b) If d is chosen to minimize the period and then L is increased, does the period increase, decrease, or remain the same? (c) If, instead, m is increased without L increasing, does the period increase, decrease, or remain the same?A 0.500-kg mass is suspended from a string, forming a pendulum.
