I'm posting these as images because it would be difficult to type. If this isn't allowed, please let me know. I really need help with this before tomorrow, when I have a test. Any help appreciated. 1. The problem statement, all variables and given/known data problem here 3. The attempt at a solution I completed part 1 (solution here) but I cannot get anywhere with part 2. I tried fsimply calculating the Laplace transforms of the results from part 1 and then manipulating them, but I got nowhere. Any help is appreciated.
