A1.6 kg block on a horizontal frictionless surface is attached to an ideal massless spring whose spring constant is 190 n/m. the block is pulled from its equilibrium position at x= 0.00m to a displacement x = +0.080 m and is released from rest. the block then executes simple harmonic motion along the horizontal x-axis.
a) what is the velocity of the block at time t = 0.40s?
b) what is the period of the motion?

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.
