An object on earth falls with an acceleration of a = 9.81 m/s². A function exists between the height from
%3D
which the object falls, the initial velocity of the object, and the time the object spends in the air.
h(t) = Vot + at²
Vo = initial velocity

%3D
t = time
a = acceleration due to gravity
Lucy and Kim determine the height of a building by dropping a brick from its roof. The initial velocity will be
0 m/s because Lucy will simply let go of the brick. Kim times the fall of the brick to be 3.5 seconds.
