We have a rule of mass m and length l lying on a table without friction.
We give a boost I to the rule at a distance d from the center of mass so that it now has a rotation and a translation.
1) The rule rotates about which point?
2) Determine the velocity, vm, of the center of mass.
3) Determine the angular velocity, w, of the ruler.
4)What should be the distance d so that the instantaneous displacement ds of the oposite side of the ruler be a minimum?
I= Variation momentum
The Attempt at a Solution
I think the answer to 1 is that it rotates about it center of mass but I don't have a clue about the other ones
