Homework Help: Newton's laws

  1. Jun 16, 2004 #1
    Here's there problem:
    You are running, your weight is 800 N. You generate a backward and downward force of 1000 N at an angle of 15 degrees from vertical. What is the maximum friction force you can generate and the actual fritction force generated between the surface area and your shoe. Coefficient of friction=0.09

    im not sure how to start this i have been using the F=ur but im not sure how the angle works into everything. Thank You sooooooo much :cry:

    But can you draw the figure and list all the forces applied to You ?
    I think I can help you, but first you should draw and post the picture...

    I think, for Ox, you have F=urSin15
    for Oy you have F=urCos15
