Once again we have a skier on an inclined plane. the skier has mass m and starts from rest. her speed at the bottom of the slope is 12.0 meters/second. the hill is inclined 30 degrees from the horizontal and the length of the slope is 100.0 meters. use the law of conservation of energy to determine her final speed and write that number down here:

Total solidification times of three casting geometries are to be compared: a sphere, a cylinder, in which the length-to-diameter ration - 1.0, and a cube. volume = 1000 cm^3 for all three shhapes, and the same casting alloy is used. a) determine the solidification times of each geometry b) based on the results of part (a), which geometric element would make the best riser? c) if the mold constant = 3.5 min/cm^2 in chvorinov's rule, compute the total solidification time for each casting.
