Question

A rod of mass M and length L lies on a smooth horizontal table, hinged about a vertical axis and free to rotate. A particle hits the rod perpendicular to its length at distance x > 0 from the hinge. Which statements are correct?

TestHub · Accepted Answer

The hinge impulse prevents general conservation of linear momentum, while angular momentum is always conserved about the hinge.

At the centre-of-percussion impact point, the hinge impulse is zero.

For that single x, linear momentum is conserved and angular momentum is conserved about infinitely many fixed points.
