Homework Help: Soccer ball question: hypotenuse/adjacent and opposite lengths

  1. Feb 18, 2010 #1
    Jake kicked a soccer ball into the air at an angle of 45 degrees to the horizontal with an intial result velocity of 30 m/s. Find both the vertical and horizzonatal components of the velocity vector. Hint: the angle of your interest is 45 degrees and you want to find adjacent and opposite lengths with the given hypotenuse 30 m/s.

    Thanks for any help provided.

    The question pretty much says everything...

    draw a diagram, label the hypotenuse as your velocity and solve,

    If you're still having trouble, use trig.

    Yeah, I figure this is really simple. We've had one class and this is the first homework. I haven't had math in 4 years and even then I struggled. Not seeing how to do this but I'll figure it out somehow. Thanks.

    I did make a diagram, have the hypotenuse and 30m/s labeled but thats it.
