Three point masses lie along a rigid, massless rod of length L = 5.61 m :(adsbygoogle = window.adsbygoogle || []).push({});

- Two particles, both of mass m = 2.1 kg, lie on opposite ends of the rod.

- Mass M = 7.29 kg is in the center of the rod.

Assume the rod lies along the x-axis, and rotates about the y-axis. about a point 1.28 m from one end at constant angular speed ω = 5.38 rad/s.

Find the kinetic energy of this system

could someone explain the ( about a point 1.28m from one end) . dose the distance 1.28 contribute any Kinetic energy to the system?

thank you so much
