1.How much subsidence would be expected from an elastic confined aquifer that has a specific storage of 2.0*10^-6 (ft^-1), a decline in pressure of 200 (lbs/in^2), and aquifer thickness of 400 ft, and a porosity of 32 percent? Assume the aquifer temperature is 20 degrees C.
2.The speed of a car traveling along a straight line is v=(3t^2-6t) ft/s, where t is in seconds.
If s=4 ft when t=0, what is the position of the car when t=4 s? Also, what is the total distance traveled during the time interval t=0 to t=4 s? What is the acceleration when t=2 s?
