Chapter 12A, Problem 2PLA

The mass m shown in Figure 12A-1 oscillates on a spring of spring constant k with amplitude A about the equilibrium position yo between the points y = yo + A and y = yo A. Choose the correct statements about the kinetic energy K, the spring potential energy US, and the gravitational potential energy UG for this motion (Questions 1-4).

2. The gravitational potential energy UG is (a) maximum at y = yoA. (b) zero at y = yo + A. (c) minimum at y = yo + A. (d) zero at y = yo.

5A = Material point of mass m moves under the influence of force F-kr = –krî With in other words, the mass m is at the tip of an isotropic harmonic oscillator with equilibrium position at the origin of the axes. a) Calculate the potential energy V(r) of m. b) To design qualitatively 1) the potential energy V(r) of the mass m, 2) its "centrifugal" dynamic energy (r) = 1² /2mr² where L is the measure of angular momentum of the mass m and r its distance from the origin of the axes, and 3) the active potential energy of U(r) = V (r)+ Vä(r).

An oscillator moves back and forth between the 10 cm and 50 cm marks on a meter stick. What is the location of the EP on the meter stick? In Problem 11, what is the amplitude A?
In Problem Set 2a you analyzed a pendulum by expanding out the gravitational potential energy V (x). An alternate way of approaching this problem is by directly considering the restoring torque T: T= -mgl sin 0. Angles and lengths are as depicted in the figure below. Gravitational restoring torque t: (a) Expand out T(0) as a power series to third order in 0. (b) Using the information from your answer to (b), determine whether the period of this pendulum at high amplitudes 69 is longer, shorter, or the same as the period at low amplitudes. Hint: The dynamics of this problem are governed by Newton's second law for angular motion T = Ia = ml²6, which is to say that the torque is directly proportional to the pendulum's instantaneous angular acceleration.
