Tom the cat is chasing Jerry the mouse across
a table surface 2.4 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 acceleration of gravity is 9.8 m/s
And what speed will he have just before hitting the ground?
how long does it take to fall 2.4m?
4.9t^2 = 2.4
during that time, Tom will travel at 4.8 m/s horizontally.
The vertical component of the velocity is v=9.8t
Now just add the two components to get the resultant velocity.
