An air-track glider attached to a spring oscillates between the 15.0 cmcm mark and the 56.0 cmcm mark on the track. The glider completes 10.0 oscillations in 31.0 ss . What are the (a) period, (b) frequency, (c) amplitude, and (d) maximum speed of the glider

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.
