Any value greater or equal than zero for their bid. Announcing a bid is costly for the bidder: if the bidder announces a bid, she incurs a cost c, where wB > c. Passing is free, but the bidder cannot win the object if she passes. If both bidders pass, no bidder wins the object. Otherwise, the bidder with the highest or the final bid wins the object. The auctioneer's payoff is the price at which the object is sold (the winning bid). Bidders maximize their final profit. If a bidder compares two outcomes with the same profit, she prefers the one where she wins the object. The auctioneer calculates the Subgame Perfect Equilibria of this auction and maximizes the price by which it sells the object in these equilibria. (a) How much does each bidder earn in each of the following cases: if she wins, if she bids but is outbid, or if she passes? (b) Assume that bidder A moves first. Find the Subgame Perfect Equilibrium of the auction and describe the strategies used in this SPE. How much do the auctioneer and each bidder earn in this equilibrium? (c) Which bidder would the auctioneer choose to move first? Why? Remember that the auctioneer maximizes the price she can get in the Subgame Perfect Equilibria of this auction. (6 points) (d) Assume as in part (b) that bidder A moves first. Is there a Nash equilibrium of this game in which the object is won by bidder B? If yes, describe the strategies of the bidders in this equilibrium. If not, explain why. Assume now that the auction has three stages: one bidder moves first, the other bidder moves second, and finally, the first mover moves again. Everything else is the same. (e) Which bidder would the auctioneer choose to move first in this case? Why?

Problem 6 (20 points) The height of a projectile fired at an initial velocity, $V_0$, and an angle, $\theta$, is a function of time, $t$: $\text{height}(t) = tV_0 \sin(\theta) - \frac{1}{2}gt^2$ where $g$ is the acceleration due to gravity, 9.8 $m/s^2$. For an initial velocity of 75 m/s, create an appropriately formatted graph of the height of a projectile vs. time for firing angle (in radians) of $\pi/6$. Assume the projectile starts at a height of 20 meters, as if the launcher is on the top of a hill. Adjust your results so that the height of the projectile cannot go below 0 meters. Once the projectile has fallen back to earth, it cannot continue to fall. Find the total time taken by the projectile to return to earth and display that in the command window. Also, select an arbitrary point on the projectile graph (using mouse), display the height and the corresponding time value at that point.

Three blocks are in contact on a flat horizontal surface. A horizontal force F = 665 N is applied to block A which has a mass of 85 kg. Block B is 110 kg and block C is 15 kg. There is a coefficient of kinetic friction between the blocks and the floor of 0.16. Calculate the magnitude of the force of contact between block A and B. (Round answer to 1 decimal place, use g = 9.8m/s²)

Electric power is to be produced by installing a hydraulic turbine-generator at a site 66 m below the free surface of a large water reservoir that can supply water at a rate of 1580 kg/s steadily (Figure given below). If the mechanical power output of the turbine is 835 kW and the electric power generation in 765 kW, find the combined turbine-generator efficiency of this plant. Ignore losses in the pipes.
