Kaitlin is going off to her physics class, jogging down the sidewalk at a speed of 3.30m/s . Her husband Scott suddenly realises that she left in such a hurry that she forgot her sandwich, so he runs to the window of their apartment, which is a height 35.0m above the street level and directly above the footpath, to throw it to her. Scott throws it horizontally at a time 5.50s after Kaitlin has passed below the window, and she catches it on the run. You can ignore air resistance.
[1]With what initial speed must Scott throw the sandwich so Kaitlin can catch it just before it hits the ground?
[2]Where is Kaitlin when she catches the sandwich?
