Problem 26E A harmonic oscillator has angular frequency ? and amplitude A. (a) What are the magnitudes of the displacement and velocity when the elastic potential energy is equal to the kinetic energy? (Assume that U = 0 at equilibrium.) (b) How often does this occur in each cycle? What is the time

Paris versus Detroit Suppose the benefi t and cost curves of the high-income households shown in Figure 7A2 are relevant for Detroit. In contrast, high-income households in Paris take 50 percent more trips to the city center (for work and cultural opportunities). While Detroiters commute in air-condi

The 19th century brought many changes in commuting, from walking to omni- buses, electric trolleys (streetcars), and subways. a. For each commuting method, draw a housing-price curve for a monocentric city, labeling each curve with the date on which the method was introduced. b. Over time, the feasib

An archaeologist sometime in the future analyzes the iron used in an old building. The iron contains tiny amounts of nickel-63, with a half-life of 92 years. On the basis of the amount of nickel-63 and its decay products found, it is estimated that about 0.78% (1/128) of the original nickel-63 remain
