Question

A cat chases a mouse across a 1.1 m high
table. The mouse steps out of the way, and
the cat slides off the table and strikes the floor
2.2 m from the edge of the table.
The acceleration of gravity is 9.81 m/s2 .
What was the cat’s speed when it slid off
the table?
Answer in units of m/s.

Answer 1

How long did it take it to fall?
1.1 = 4.9 t^2
Solve for t

How far did it for at constant horizontal speed u?
2.2 = u t
u = 2.2/t , same t

Answer 2

4.64
