Figure 6(a) shows a circuit where 1, 2, 3, 4 = 1 V, 2 V, 3 V, 4 V respectively and 1, 2, 3, 4, 5, 6 = 1 Ω, 2 Ω, 3 Ω, 4 Ω , 5 Ω, 6 Ω respectively. Calculate the current passing through 6

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.)
