Tom the cat is chasing Jerry the mouse across
a table surface 1.9 m off the floor. Jerry steps
out of the way at the last second, and Tom
slides off the edge of the table at a speed of
Where will Tom strike the floor? The ac-
celeration of gravity is 9.8 m/s2 .
Answer in units of m
Calculate how long (T) that it takes Tom to hit the ground. This depends only upon the height (H) and g, since the cat takes off horizontally.
(1/2) g T^2 = H
T = sqrt(2H/g)
Then multiply T by the horizontal velocity component of Tom, which remains constant at 4.6 m/s.
2.9 m is your answer.
