Explanation:
Kepler’s third law states that for all objects orbiting a given body, the cube of the semimajor axis (A) is proportional to the square of the orbital period (P). 
For each of our planets orbiting the Sun, the relationship between the orbital period and semimajor axis can be represented by the equation as:

k is constant of proportionality
It is required to solve the above equation for k

 
        
             
        
        
        
-- It takes the brick 8.9 seconds to reach the ground.  
-- At the instant of the "splat", it's falling at 89 m/s.
-- The mass doesn't matter. If not for air resistance, every object 
    would fall at the same rate.  The answer is the same for a feather, 
    a rubber chicken, a brick, or a school bus.
