Suppose the current price of a marketable permit to emit one ton of sulfur dioxide is $100. If the marginal cost for a firm to reduce one ton of sulfur dioxide is $80, then: the firm will be willing to pay up to $200 for a permit. the firm will shut down. the firm will buy the permit and increase its emissions by 20 tons. the firm will reduce its emissions of sulfur dioxide by one ton. the firm will buy the permit and emit one more ton of sulfur dioxide.

Problem 5: You place your ear onto a steel railroad track and hear the sound of a distant train through the rails ?t = 4.5 seconds faster than you do through the air. The speed of sound in steel is v_s = 6100 m/s while in air the speed of sound is v_a = 343 m/s. Part (a) Write an equation for the time it takes the sound to reach you through the air if the distance to the train is represented by D. Part (b) Write an equation for the time it takes the sound to reach you through the steel if the distance to the train is represented by D. Part (c) Use the difference in these two times to write an equation for the distance to the train. Part (d) For the given information find the distance to the train in meters.

Some parameters to work with are the following. At the beginning of the spin, the skater can be approximated as a cylinder with a radius of 9 cm and mass of 39 kg (accounting for head, trunk, and vertical leg) plus two rods perpendicular to the axis of rotation, each with length 63 cm and mass 2 kg (accounting for arms), and one rod perpendicular to the axis of rotation with length 82 cm and mass 12 kg (accounting for the extended leg). At the end of the spin, the skater can be approximated as a single cylinder with a radius of 21 cm and mass of 55 kg. At the beginning of the spin (from 3-6 seconds on the video clip), Dorothy Hamill is spinning at about 1.8 revolutions per second. A) Determine the moment of inertia of Hamill at the beginning of the spin. Label this as Ii. You will need the moment of inertia for a cylinder and a rod (note that the rods have their axis of rotations at the end of the rods, not the center of the rods). B) Determine the moment of inertia of Hamill at the end of the spin. Label this as If. You will need the moment of inertia of a cylinder (same as a disk). C) What is Hamill’s angular velocity at the beginning of the spin in rad/s? D) Assuming angular momentum is conserved, determine Hamill’s angular velocity at the end of the spin in both rad/s and revolutions/second. Does this seem consistent with the video? E) Calculate the rotational kinetic energy of Hamill at the beginning and end of the spin. F) Does Hamill gain or lose rotational kinetic energy? If there is a change in rotational kinetic energy, there must be work done. What work is being done to change the rotational kinetic energy? (Hint: consider question 5 from the Week 9 Sapling homework or consider any past experience of moving toward the center of a speeding merry-go-round.)

Activity 2. Solve the following problems. 1. The mean number of hours a Filipino worker spends on the computer is 3.1 hours per workday. Assume the standard deviation is 0.5 hour and is normally distributed, how long does a worker spend on the computer if his z-score is 1.2? 2. Each month, a Filipino household generates an average of 28 pounds of newspaper for garbage or recycling. Assume the standard deviation is 2 pounds. Determine the z-score of a household that generates 22 pounds of newspaper. 3. The Candelaria Automobile Association reports that the average time it takes to respond to an emergency call is 30 minutes. Assume the variable is normally distributed and the standard deviation is 4.5 minutes. How long will a call be responded if it has a z-score of 0.75? 4. The average monthly salary for newly hired teachers is P21,945. If the distribution is approximately normal with a standard deviation of P3250. How much will a teacher earn in a month if his salary has a z-score of 1.15?
