A hard-boiled egg of mass 48.0 g moves on the end of a spring with force constant 25.0 N/m . The egg is released from rest at an initial displacement of 0.305 m . A damping force Fx=−bvx acts on the egg, and the amplitude of the motion decreases to 0.113 m in a time of 4.70 s . Calculate the magnitude of the damping constant b.
b = kg/s
