## Homework Statement

An rectangular object(mass m) sliding on a horizontal plane (surface is frictionless), with a speed V, object height H.

then hits a rectangular obstacle with height h. V is large enough to cause tripping

## Homework Equations

what is the relation between linear momentum / angular momentum / conservation of momentum

## The Attempt at a Solution

is this what's happening; the object has a momentum of P=mV.

then an impulse I=t*F is applied to the object by the obstacle.

This impulse reduces the linear momentum to P'=m*V-F*x

---This m*V-Fx gives the angular momentum(with respect to the point of contact) causing the rotation?---

I am not sure if my thinking is correct, especially my last statement.

An alternative is; taking initial mV as an angular momentum with changing radius wrt the contact point? ie not mentioning linear momentum at all?

Thanks in advance.
