Make appropriate sketches in the BCC system to show which members of the <111> family of directions lie within the (110) plane Repeat the problem for the (0-11) plane. Sketch these planes showing the atoms and the directions.

Amass weighing 24 pounds, attached to the end of a spring, stretches it 4 inches. initially, the mass is released from rest from a point 8 inches below the equilibrium position. find the equation of motion. (use g = 32 ft/s2 for the acceleration due to gravity.)
