A 55.0 g hard-boiled egg moves on the end of a spring with force constant 25.0 N/m. Its initial displacement 0.500 m. A damping force Fr =-bvx acts on the egg, and the amplitude of the motion decreases to 0.100 m in a time of 5.00 s. Part A Calculate the magnitude of the damping constant b. Express your answer in kilogram per second. b = kg/s
