a cat chases a mouse across a 1.4 m high table. the mouse steps out of the way, and the cat slides off the table and strikes the floor 1.7 m from the edge of the table. the acceleration of gravity is 9.81 m/s 2 . what was the cat’s speed when it slid off the table? answer in units of m/s.

how long does it take to fall 1.9m?

4.9t^2 = 1.9
now you use that value of t to find v:
vt = 1.7
