Question description
A thin rod lies at rest along the x axis with one end at x = -a and the other end at x = a, where a = 2.66 m. The rod has a non-uniform density given by λ(x) = β(x+a)2, where β=0.33 kg/m3.Find the moment of inertia of the rod about an axis passing through the origin.I =______ kg-m2At t = 0, a constant angular acceleration of 8.00 rad/s2 is applied to the rod. Find the kinetic energy of the rod at t = 10 s.K =______ kJ
