Amass weighing 64 lb is attached to a spring hanging from the ceiling and comes to rest at its equilibrium position. at time tequals0, an external force of upper f (t )equals3 cosine 5 t lb is applied to the system. if the spring constant is 10 lb/ft and the damping constant is 2 lb-sec/ft, find the steady-state solution for the system. use g equals 32 ft divided by sec squared.

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. a) reforestation would not benefit many species because most forest species live on the ground. b) reforestation would take the longest time to be effective because trees take several years to grow. c) biological augmentation would benefit only a few species because is is typically not very effective. d) biological augmentation would take less time to ve effective because it targets the majority of prey species.
