Homework Help: Physics Problem: Magnitudes and Components

  1. Nov 20, 2007 #1
    A hammer slides down a roof that makes a 32.0 degree angle with the horizontal.

    a.) What are the magnitudes of the components of the hammer's velocity at the edge of the roof if it is moving at a speed of 6.25 meters per second?

    b.) Calculate the components of the hammer's velocity at the edge of the roof.

    I have drawn a picture and attempted to do this problem but i'm not exactly sure where to start. Any help is appreciated!

    I attempted to do this, but I think I just forced numbers (I know my picture is correct because the teacher gave it to us as a hint). I currently have Vy=6.25sin32.0 (3.44 m/s) with a magnitude of 32.0 degrees and Vx=6.25cos32.0 (5.21 m/s) with a magnitude of 58 degrees.

    I think this solution is right.It maybe more complicated if it falls from roof.

    Thanks for the help. I don't have to take into account the hammer falling off the roof.
