The figure above shows the cost curves of a perfectly competitive firm in the coffee markot. Use the graph in Figure 10.20 to answer the following questions. Assume the market price is \( \$ 3 \) par pound. a. What is the lowest price at which the coffee grower will supply output in the short run? b. In the diagram, draw the firm's demand curve (label this "MR" for marginal revenue). c. What is the firm's profit-maximizing output? d. Is the firm earning a profit or a loss? Identify the area in the graph that represents the firm's profit or loss. e. Explain how entry or exit will occur in the market to ensure that firms will break even in the long run.

The 0.75 kg ball is attached to the 0.25 kg slender rod OA which pivots freely about a horizontal axis through point O. The system is released from rest while in the position ??? = 0 where the spring with k = 50 N/m is unstretched. a) If the ball is treated as a particle and the mass of the rod neglected, what is the velocity of the ball as it passes the position ??? = 30°? b) If the ball has a diameter of D = 0.12 m, what is the velocity of the ball's centre of mass as it passes the position ??? = 30°?
