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.

$2gh = v_{f}^2 - v_{i}^2$

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,

$2(9.81\ m/s^2)h = (6.5\ m/s)^2 - (0\ m/s)^2\\h = \frac{(6.5\ m/s)^2}{(2)(9.81\ m/s^2)}$

This question may require more information for an accurate answer. If the clouds are observed west of the city and they are moving in a westerly direction it means that the clouds are moving away. Precipitation refers to rainfall, sleet, hail or snow. Since no reference was made to the temperature, season or location of the city it could be rain or snow clouds. The clouds are moving away from the city so the possible answers could be b. or d. Furthermore, by dividing the distance by the speed one would get an answer of twenty four hours. So even if the clouds were moving towards the city it would take a day to reach and precipitation would not be likely in 24 hrs.
