Final answer:

To calculate the time it took for Rex's mother's vase to reach the ground from the 4th story, use the formula t = sqrt(2h/g), where h is the height and g is acceleration due to gravity.


Explanation:

To determine the time it took for the vase to reach the ground:

  1. Calculate the time taken to fall from the 4th story to the ground using the formula t = sqrt(2h/g), where h is the height and g is acceleration due to gravity (9.81 m/s^2).
  2. Substitute the values: h = 180 m, solve for t, giving you the time taken for the vase to reach the ground.
