In Arizona, severe drought conditions have often prompted officials to question whether the operation of public swimming pools should be permitted. As the chief engineer of the State of Arizona that has a large number of public pools, you have been asked to estimate the daily water loss due to pool evaporation. As representative conditions, you may assume water and ambient air temperatures of 30 oC, an ambient relative humidity of 10 %, pool surface dimensions of 6 m by 12 m, and a wind speed of 2 m/s in the direction of the long side of the pool. Assume the free stream turbulence of the air to be negligible and the surface of the water to be smooth and level with the pool deck. Estimate the water loss for the pool in kg/day.

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 790 n/m. it is initially at rest on an inclined plane that is at an angle of 28 degrees with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is k = 0.14. in the initial position, where the spring is compressed by a distance of a = 0.18 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. b) if the spring pushes the block up the incline, what distance, l, in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.
