1.The storativity of the Jordan Aquifer (a regional confined aquifer) is 5 x 10-4 and the porosity is 0.3. The thickness of the aquifer is 200 ft.
a)If the head in the Jordan has been pumped down by 100 ft in recent times, how much water in cubic feet has been pumped out of storage for an area of 100 sq. mi.?
2.The two particles A and B start at the origin O and trevel in opposite directions along the circular path at constant speeds va =.7 m/s and vb =1.5 m/s . Determine the time when they collide and the magnitude of the accelerartion of b just before this happens.
3.Car traveling along a circular curve that has a radius of 50m. if its speed is 16m/s and is increasing uniformly at 8 m/s^2 determine the magnitude of its acceleration at this instant.
