How Does an Impulse Affect the Motion of a Cube?

[sabatier]

I'd be grateful if someone could help me with the problem below:

A free-floating uniform cube with sides of length 2 is at rest,
aligned with the coordinate axes, when it is subjected to an
impulse along one edge of 3m, where m is its mass. What
is the effect on its motion? (Its inertia tensor is 2/3mI)

Do I calculate the angular velocity or what? And how?

Thanks for any help.

Hi sabatier! Welcome to PF!

(how can impulse have dimensions of mass? )

You have to calculate the velocity of the centre of mass, and the angular velocity (including specfiying the axis of rotation) relative to the centre of mass.
