Unless there was some previously different speed or direction, and some sort of collision, there is no change in momentum.
Did you omit a previous set of facts about this problem? Was there some sort of event that is "sustained" ?
Midterm review time!
I just can't manage to get this question.
"A 12kg shopping cart rolls due south at 1.5m/s, 30 degrees E of S. What is the magnitude of the change in momentum sustained by the shopping cart?"
I know momentum equals the mass times the change in velocity, but I'm not sure how to get the correct velocity?
