Question

A mass 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.

Answer 1

spring constant = 24/4 = 6 pounds/inch

amplitude of SHM should be 8 inches.

y = 8 sin omega t

omega to be found. Massspring has frequency related to spring constant and mass ...
