Answer:

h = 2.15 m

Step-by-step 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.


2gh = v_(f)^2 - v_(i)^2

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,


2(9.81\ m/s^2)h = (6.5\ m/s)^2 - (0\ m/s)^2\\h = ((6.5\ m/s)^2)/((2)(9.81\ m/s^2))

h = 2.15 m
