Consider the following rotational mass-spring-damper system, where ( J=0.2 , kg ⋅ m² ), ( b=1 , N ⋅ m ⋅ s/rad ), and ( k=2 , N ⋅ m/rad ). At time ( t=0 ), suppose the rigid body is given an angular twist, ( θ(0)=θ₀ ), and t...

a) ( 0.2 , kg ⋅ m² )
b) ( 1 , N ⋅ m ⋅ s/rad )
c) ( 2 , N ⋅ m/rad )
d) ( θ₀ )
