Homework Statement
Four equal discs of mass
Answer: The center of mass moves with constant velocity
Homework Equations
Linear momentum:
Angular momentum:
Impulse-momentum theorem:
The Attempt at a Solution
I obtained the first result by assuming that the the linear momentum transmitted by the impulse will be divided into four chunks, which will be associated with each mass. Then, the center of mass will notably move with velocity
