Another vector problem

  1. Oct 3, 2004 #1
    another vector problem (check if I'm correct)

    A quarterback takes the ball from the line of scrimmage, runs backward for 10.0 yards, then runs sideways parallel to the line of scrimmage for 15.0 yards. At this point, he throws a 50 yard forward pass straight downfield, perpendicular to the line of scrimmage. What is the magnitude of the football’s resultant displacement?

    Is it about 52? Since I used [tex]a^2 + b^2 = c^2[/tex]

    [tex]50^2 + 15^2 = c^2[/tex]

    the figure i get in my head is something like
    A |......
    ...|.....|C
    B |___|D

    AB = 50
    CD = 10
    BD = 15
    u are supposed to find AC

    ahh after looking at your diagram it should be

    [tex]40^2 + 15^2 = c^2[/tex]

    about 43 then
