The height of the building in meters, given the data is 108 m

Data obtained from the question

  • Mass (m) = 7 Kg
  • Time (t) = 4.7 s
  • Acceleration due to gravity (g) = 9.8 m/s²
  • Height (h) = ?

How to determine the height of the building

The height of the building can be obtained as illustrated below:

h = ½gt²

h = ½ × 9.8 × 4.7²

h = 108 m

Thus, the height of the building is 108 m
