A cat chases a mouse across a 1.5 m high

Question

table. The mouse steps out of the way, and
the cat slides off the table and strikes the floor
1.0 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

Answer 1

since the horizontal distance is d = vt, we need to know how long it took to fall 1.5m.

s = 1/2 at^2 = 4.9 t^2 = 1.5
t = .55 sec

So, 1 = .55v
v = 1.82m/s
