Tom the cat chases a Jerry the mouse across a 1.2m high table. Jerry steps out of the way at the last second, and Tom slides off the table and strikes the floor 1.5m from the edge of the table.
(a) How long did it take Tom to hit the floor?
(b) What was Tom's speed when he slid off the table?
(c) What was the direction of Tom's velocity just before he hit the floor?
