SUMMARY

The discussion revolves around calculating the rotation rate of a dumbbell consisting of two masses, m1 and m2, when an impulse force F is applied to m1 in the negative y direction. The participants clarify that while m1 experiences a change in momentum, m2 remains unaffected during the impulse due to the perpendicular application of force. The conversation highlights the importance of understanding conservation of momentum, both linear and angular, and concludes that the angular velocity can be derived from the relationship between the linear velocity of m1 and the center of mass.

hah! thank you so much. I had gotten to the solution but I needed some justification for it and you gave it to me. No more questions from my part. Cheers
