A one half 1 2-kg mass is attached to a spring with stiffness 5050 N/m. The damping constant for the system is 88 N-sec/m. If the mass is moved five twelfths 5 12 m to the left of equilibrium and given an initial leftwardleftward velocity of eight thirds 8 3 m/sec, determine the equation of motion of the mass and give its damping factor, quasiperiod, and quasifrequency.

Consider the growth of a 20-nm-diameter silicon nanowire onto a silicon wafer. the temperature of the wafer surface is maintained at 2400 k. assume the thermal conductivity of the silicon nanowire is 20 wm-1k-1 and all its surfaces including the tip are subjected to convection heat transfer with the coefficient h = 1×105 wm-2k-1 and t∞ = 8000 k. when the nanowire grows to l = 300 nm, what is the temperature of the nanowire tip (t (x =
