Having trouble figuring this one out: A playful cat sees a mouse run past him with a constant velocity of 2 m/s. One second after the mouse passes the cat, the cat jumps after the mouse at an angle of 30 degrees and some unknown initial velocity. Being a naturally-talented cat, he lands perfectly right where the mouse ends up (the mouse didn't think to turn or change his speed). What is the initial velocity of the cat?
