(25 pts.) During a football exhibition game, Alfred catches the football while standing directly on the goal line. He immediately starts running forward with a constant acceleration of 2 m/s2. At the moment the catch is made (t = 0), Bruce is 20 m away and heading directly toward Alfred with a steady speed of 5 m/s. Neither deviates from a straight-ahead path. a. (6 pts.) Consider a coordinate system where Alfred’s initial position si = 0. What are the values of the kinematic variables for Alfred and Bruce?

An import car dealer sells three models of a car. The retail prices and the current dealer invoice prices (costs) for the basic models and options indicated are given in the following two matrices (where "Air" means air-conditioning). We define the markup matrix to be M - N (markup is the difference between the retail price and the dealer invoice price). Suppose that the value of the dollar has had a sharp decline and the dealer invoice price is to have an across-the-board 15% increase next year. To stay competitive with domestic cars, the dealer increases the retail prices 10%. Calculate a markup matrix for next year's models and the options indicated. Retail Price Dealer invoice price AM/FM Cruise AM/FM Cruise Basic Car Air Radio Control Basic Car Air Radio Control Model A $30,627 $2281 $891 $545 Model A $35,706 $2556 $1278 $641 Model B $34,756 $1546 $698 $340 Model B $39,119 $1872 $759 $519 = M Model C $41,483 $2835 $1201 $668 Model C $45,592 $3326 $1434 $884 Calculate a markup matrix for next year's models. Select the correct choice below and, if necessary, fill in the answer box(es) to complete your choice. A.

1. Assuming a cytosolic NADH leads to the production of 2.5 ATP, how many ATP would ultimately be produced per one glucose just from glycolysis? 2. Assuming a cytosolic NADH leads to the production of 1.5 ATP, how many ATP would ultimately be produced per one glucose just from glycolysis? 3. How many ATP would ultimately be produced per one glucose just from the pyruvate dehydrogenase reaction? 4. How many ATP would ultimately be produced per one glucose just from the citric acid cycle? 5. Assuming a cytosolic NADH leads to the production of 2.5 ATP, how many ATP total (i.e., the net gain of ATP) would ultimately be produced per one glucose assuming it has gone through glycolysis, the PDH reaction, and the citric acid cycle? 6. Assuming a cytosolic NADH leads to the production of 1.5 ATP, how many ATP total (i.e., the net gain of ATP) would ultimately be produced per one glucose assuming it has gone through glycolysis, the PDH reaction, and the citric acid cycle? 7. How many ATP would be produced for one glyceraldehyde 3-phosphate proceeding through glycolysis, the pyruvate dehydrogenase reaction, and the citric acid cycle with the electrons from oxidation entering the electron transport chain. Assume that the cytosolic NADH leads to the production of 2.5 ATP.

Consider a right triangle of base $L$ and height $H$, as shown in the right figure. The triangle has a nonuniform surface density $\sigma = \sigma_0 x/L$, where $\sigma_0$ is a constant of dimension mass per area. Find the total mass of the right triangle. Consider a L-shape bracket as shown in the right figure. The bottom end of the bracket is aligned on the x-axis with a nonuniform mass density $\lambda(x) = \lambda_0 \frac{x^2}{L^2}$, while the vertical end is aligned on the y-axis with a uniform mass density $\lambda_0$. The constant $\lambda_0$ has a dimension of mass per unit length. Find the center of mass of the L-shape bracket.

Two thin conducting wires shaped as cylinders with radii $r_0$, separated by distance $b$ from each other, are attached to a large conducting slab of thickness $a$, where $a \ll r_0 \ll b$. Estimate the resistance between the wires, assuming that the conductivity of the wires $\sigma_0$ is much larger than the conductivity of the slab $\sigma$. (7 points)
