Consider the projectile of Section 2.3. (a) Assuming there is no air resistance, write down the position (x, y) as a function of t, and eliminate t to give the trajectory y as a function of x. (b) The correct trajectory, including a linear drag force, is given by (2.37). Show that this reduces to you

Consider a monocentric city where the cost of commuting is $40 per mile per month. A household located eight miles from the city center occupies a dwell- ing with 1,000 square feet at a monthly rent of $600. Nonland cost per dwelling is $250, and there are 10 houses per hectare. a. The price of housi

Ernie owns a water pump. Because pumping large amounts of water is harder than pumping small amounts, the cost of producing a bottle of water rises as he pumps more. Here is the cost he incurs to produce each bottle of water: Cost of first bottle - $1 Cost of second bottle - $3 Cost of third bottle
