A particle moves along a straight line such that its acceleration is a = (4t^2-2) m/s, where t is in seconds. When t = 0, the particle is located 2 m to the left of the origin, and when t = 2, it is 20 m to the left of the origin. Determine the position of the particle when t=4s.

S1.1 The Acre-Foot. Hydraulic engineers in the United States often use, as a unit of volume of water, the acre-foot, defined as the volume of water that will cover 1 acre of land to a depth of 1 ft. A severe thunderstorm dumped 2.0 in. of rain in 30 minutes on a town of area 26 km2. What volume of water, in acre-feet, fell on the town? S1.2 The Thunderstorm. What mass of water fell on the town in S1.1The Acre-Foot during the thunderstorm? One cubic meter of water has a mass of 103kg.

In a manufacturing facility, 2-in-diameter brass balls (k = 64.1 Btu/h·ft·°F, rho = 532 lbm/ft^3, and cp = 0.092 Btu/lbm·°F) initially at 360°F are quenched in a water bath at 120°F for a period of 2 min at a rate of 120 balls per minute. The convection heat transfer coefficient is 42 Btu/h·ft^2·°F. Take I to be the initial temperature. Determine:

a. The temperature of the balls after quenching.

b. The rate at which heat needs to be removed from the water in order to keep its temperature constant at 1200F.
