A hard-boiled egg of mass 52.0 moves on the end of a spring with force constant 24.8 . The egg is released from rest at an initial displacement of 0.300 . A damping force Fx=-bvx acts on the egg, and the amplitude of the motion decreases to 0.104 in a time of 5.15 . Calculate the magnitude of the damping constant b.
