Relativity: A bus with a vertical windshield

  1. Jan 21, 2013 #1
    1. The problem statement, all variables and given/known data
    A bus with a vertical windshield moves along in rainstorm at speed V relative to the ground. The raindrops fall vertically with a terminal speed of V' relative to the ground. At what angle do the raindrops strike the windshield?


    2. Relevant equations

    Kinematics equations


    3. The attempt at a solution

    The only thing I've attempted so far is the trying to draw the diagram. Even then, I'm still confused as to how the diagram should be drawn. I'm quite lost and do not know how to approach this problem. Thanks for all the help.

    Did you draw vectors for the velocities?

    I'm really sorry, but I don't fully understand what you're saying.

    Do you understand what a vector is? You are probably getting hung up on the fact that you are only taking into account the SPEEDS but you need to combine each speed with its direction to create a (velocity) vector. Then you will have 2 vectors that will give you the answer.
