5. What range of d. values will result in a virtual image? Infer this information for both the lens and mirror based on the data collected. Report these ranges in
terms of d, distances measured in centimeters. (Ex: d. > 20 cm)
Convex Lens:
Concave Mirror:

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.)
