Construct a full model (i. e., figure out everything you can) for the motion described below.

A monorail starts from rest and accelerates at a rate of 2.2 m/s2 for 10 s. Then it
runs at a constant speed for 74 s and then slows down at a rate of 1.5 m/s2.

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.
