A 60 meter long rope hangs freely from the top edge of a 120 meter tall building. The density of the rope is 55(g)/(m). How much work is needed to pull all the rope to the top edge of the building? A 1kg bucket is lowered into a well 10 meters deep. Full the bucket contains 3kg of water. How much work is required to lift the bucket to the top of the well? Assume the weight of the rope is negligible. From the previous problem: Suppose the bucket has a leak and water leaks from the bucket at (1)/(5)k(g)/(m) at a constant. How much work is required to lift the leaky bucket to the top of the well? A water tank is shaped like an inverted cone (point down) with height 6m and radius 1.5m. If the tank is full, how much work is required to pump the water to a level (1)/(2) meter above the top of the tank? 1.

A spaceship, with specifications as in the previous problem, and of mass $M$, is moving through empty space at fixed velocity. Suddenly it enters a cloud of dust particles, at rest, each of mass $m$; the cloud itself has a mass density $\rho$. Collisions with the dust act to slow the spaceship. (For simplicity, assume that such collisions are elastic head-on collisions; that is to say that the final masses of both the ship and the dust particles are the same as their initial masses, and that the final velocities are aligned along the initial velocity of the ship. Also assume that $M \gg m$.) The spaceship captain orders the jets turned on to maintain the ship's initial velocity. If the captain has the perfectly efficient "flashlight drive" (Example 2.2) at what rate (per unit proper time) does the spaceship lose mass?

Yen/dollar exchange rate e* 0 Quantity of dollars traded Supply of dollars Demand for dollars Refer to the Figure above of the U.S. dollar market. Let's start with the initial demand curve, the initial supply curve, and initial equilibrium. If Japan experiences an economic expansion and hence incomes increases while the U.S. economy remains stagnant, then assuming all else constant, we will represent this event as leading to a rightward shift of the supply curve for dollars a leftward shift of the supply curve for dollars a rightward shift of the demand curve for dollars rightward shifts of both the demand curve for dollars and the supply curve for dollars
