students use a simple pendulum with a length of 36.90 to measure the acceleration at the location of their school. if the period of the pendulum is 1.220s what is the experimental value of g at school

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.)
