How to Solve Inverse Laplace Transforms for a Rational Function?

Click For Summary
To solve the inverse Laplace transform of the function 200/(s^2 + 10s + 200), the denominator can be rewritten as (s + 5)^2 + 175. This form allows the use of a specific identity for inverse transforms. The discussion emphasizes the importance of partial fraction decomposition to simplify the function for easier transformation. Utilizing a table of transforms will aid in finding the solution. The approach outlined provides a clear method for tackling inverse Laplace transforms of rational functions.

Thanks. Theres a identity I can use to solve it in this form.
 
Question: A clock's minute hand has length 4 and its hour hand has length 3. What is the distance between the tips at the moment when it is increasing most rapidly?(Putnam Exam Question) Answer: Making assumption that both the hands moves at constant angular velocities, the answer is ## \sqrt{7} .## But don't you think this assumption is somewhat doubtful and wrong?
