write a java code using main that meets all of the requirements

Write a program in Java calculate distance an object travelled when falling down to earth due to gravity in a certain number of seconds. Here is the formula: d=0.5gt2 where g is the graviational constant of 9.8 and ' t is the amount of time elapsed in seconds and d is the distance object had fallen in meters. First, show your algorithm. You should show the high-level steps first and each step should be a method in the implementation. Then show the refinement of further details for each step. Secondly, implement your algorithm in Java. You MAY do this implementation piecewise where you will implement one method at a time. Or try to solve the problem all at once. I do prefer the former. Note that time in seconds can be of type double so you can have values such as 10.4. Hence, your getDouble() method in question \#1 above can be re-used. Simply a copy and paste for now
