A long, uniform rod of length  0.500 mm and isrotating in a circle on a frictionless table. The axis of rotationis perpendicular to the length of the rod at one end and isstationary. The rod has an angular velocity of 0.42 rad/srad/s anda moment of inertia about the axis of 3.20×10−3kg⋅m2kg⋅m2 . An insect initially standing on the rod at the axis ofrotation decides to walk to the other end of the rod. When theinsect has reached the end of the rod and sits there, itstangential speed is 0.173 m/sm/s . The insect can be treated as apoint mass.
A) Find the mass of the rod?
B)Â Â Find the mass of the insect?
