A cat chases a mouse across a 1.0 m high
table. The mouse steps out of the way, and
the cat slides off the table and strikes the floor
2.3 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.

  1. fell one meter
    y = 1 + 0 t - 4.9 t^2
    y = 0 at ground
    so
    t^2 = 1/4.9 = 0.204
    t = .452 seconds
    2.3 meters = u (.452)
    u = 2.3 / .452
