Yo guys... long time no... read :?

Anyways, I'm stuck on this physics problem and I'm thinking it will be pretty easy for some of you guys.

It is related to momentum and impulse.

This is not a Homework problem. It is one of the odd problems (with the answer in the book) and it is similar to one of the homework problems. I need somewhere to start, I can't seem to figure this out.

A ball of mass 0.150kg is dropped from rest from a height of 1.25m. It rebounds from the floor to reach a height of 0.960m. What impulse was given to the ball by the floor?

My understanding is that impulse is in kg*m/s.

Somehow I came up with 3.57 kg*m/s which is apparently wrong.

No class for three days...

Please help....

P.S.

Since when has this site had spell check?? That's kinda handy.
