Ablock (mass m1) lying on a frictionless inclined plane is connected to a mass (mass m2) by a massless cord passing over a pulley, as shown in figure below. (a) determine a formula for the acceleration of the system of the two blocks in terms of m1, m2, theta, and g. (b) what conditions apply to masses andm1 and m2 for the acceleration to be in one direction (say, m1 down the plane), or in the opposite direction? show all work, !

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.
