The producers, produce what ever they are producing for the consumers to obtain. The decomposers, decompose the things when the producers and consumers are done with them. Therefore, it is a cycle!
To solve this problem we will apply the linear motion kinematic equations.
The equation that describes the position as a function of the initial velocity, acceleration and time is given by the relation

Here,
Initial velocity
t = Time
a = Acceleration, at this case due to gravity
There is not initial velocity then we have that the equation to the given time is


If the ball is held at a height of 1m before it is dropped, we have that the Building height is
