Answer:
h = 2.15 m
Explanation:
We can use the third equation of motion here to find out the height from which the cat fell that is the height of the refrigerator.
[tex]2gh = v_{f}^2 - v_{i}^2[/tex]
where,
g = acceleration due to gravity = 9.81 m/s²
h = height of refrigerator = ?
vf = final speed of cat = 6.5 m/s
vi = initial speedof cat vertically = 0 m/s
Therefore,
[tex]2(9.81\ m/s^2)h = (6.5\ m/s)^2 - (0\ m/s)^2\\h = \frac{(6.5\ m/s)^2}{(2)(9.81\ m/s^2)}[/tex]
h = 2.15 m
