1. Public Goods Provision and Lindahl Prices A small town is considering building a public park that benefits all three of its residents: Alice, Bob, and Carol. The park is a pure public good, meaning that once it is built, everyone can enjoy it without reducing the benefit to others. Each person has a different willingness to pay (marginal benefit) for additional acres of park space. Their marginal benefit functions are given as follows: Alice: MB=20−Q where Q is the number of acres of park space. Bob: MB=15−2Q The marginal cost (MC) of providing each acre of the park is 25. Carol: MB=10−0.5Q 1.1 Find the socially optimal provision of the park. 1.2 Calculate the Lindahl tax prices for each individual at the optimal quantity Q*. 1.3 What challenges might arise in implementing this taxation method? 1.4 How could free-riding or misreporting affect the provision of public goods?

A patch has been designed to release a drug to treat airsickness. The patch is applied an hour before the flight and is worn until the flight is over. The patch is a cylindrical disk 3-mm thick with a radius of 1 cm. The drug is initially at a concentration of 55 mM. Assume that the concentration in the adjacent skin is much less than the concentration in the patch. The diffusion coefficient of the drug in the patch is 1.1 x 10-® cms. The manufacturer must have the release rate above 0.5 × 10-10 mol s' to ensure that there is enough drug in the bloodstream for the drug to be effective. Using the data given, assess whether the desired release rate can be achieved for a 14-hour flight from San Francisco to Beijing. (Hint: Determine whether the semi-infinite medium approximation is valid.) If the criterion is not met, suggest possible ways to produce a higher flux.

[37] A cartel, consisting of firms A and B, has allocated production such that A produces 10 units (i.e., $Q_A$ = 10) and B produces 100 units (i.e., $Q_B$ = 100). Each firm has the following marginal cost equation: A's marginal cost: $MC_A = 40(Q_A)$ B's marginal cost: $MC_B = 4(Q_B)$ In order to maximize cartel (joint) profit the cartel should A. have A produce more and B produce less. B. have A produce less and B produce more. C. maintain each firm's production at their current levels.

4.6. The state of stress at a point in a cast-iron structure ($\sigma_u = 290 \text{ MPa}$, $\sigma_u' = 650 \text{MPa}$) is described by $\sigma_x = 0$, $\sigma_y = -180 \text{ MPa}$, and $\tau_{xy} = 200 \text{ MPa}$. Determine whether failure occurs at the point according to (a) the maximum principal stress criterion and (b) the Coulomb-Mohr criterion.

1- A particle starts its motion in two dimensional space with an initial velocity of 40 m/s oriented at 30° counterclockwise with respect to the x axis. The acceleration of the particle is $a = 2t\mathbf{i} - 3\mathbf{j}$ m/s², where t is time in seconds and $\mathbf{i}$ and $\mathbf{j}$ are unit vectors in the x and y directions, respectively. Calculate the rate of change of its speed and the radius of curvature of its path when t=2 seconds.
