The maximum speed of the block occurs when spring has no deformation, that is, there is no elastic potential energy, which can be remarked from appropriate application of the Principle of Energy Conservation:



Hello! :)

Use the kinematic equation below to solve for the height of the building:

Where:
d = distance, or height of the building (m)
a = acceleration due to gravity (9.8 m/s²)
t = time (seconds)
Plug in the given values into the equation:
