    My Questions:

    1- Can someone explain me why we have used Wave resistance in first part but not in 2nd part?What is condition to use it.

    2- Can someone explain me please how he solved Part 3 as I need concept of it and I am not being able to get the whole concept.

    3- What is concept of solving this type of question.

    ----------------------
    The 'wave' only occurs at t=0. At t>0 there is no 'wave' because the sender V=constant=5, so the 'wave resistance' also only occurs at t=0.
    Use the 'wave resistance' only at TIME when a wave is present.
