A free spring hangs from a support and has a length of 20 cm Attaching a mass M to the spring causes it to oscillate If the mass is attached to the free spring and then released from rest the lowest position of the oscillation is 10 cm below the free spring length a Where is the equilibrium position b What is the frequency of oscillations ans 2 2 cycles sec c What is the velocity when the mass is 5 cm below the free spring length ans 70 cm sec d A second mass of 300 gm is added to the 1st mass When this system oscillates it has half the frequency of the system with mass M alone What is the mass M ans 100 gm e Where is the new equilibrium position ans 15 cm below the old position
