A light rod of length ℓ = 1.00 m rotates about an axis perpendicular to its length and passing through its center as in the figure below. Two particles of masses m1 = 4.45 kg and m2 = 3.00 kg are connected to the ends of the rod.

(a) Neglecting the mass of the rod, what is the system's kinetic energy when its angular speed is 2.20 rad/s?
 J

(b) Repeat the problem, assuming the mass of the rod is taken to be 2.30 kg.

Thank you for the opportunity to help you with your question!

k.e =0.5mv^2

4.45 +3 =7.45

7.45 x 2.2^2 x 0.5=18.029

Please let me know if you need any clarification. I'm always happy to answer your questions.
