Biomechanics physics

  1. Dec 20, 2016 #1
    1. The problem statement, all variables and given/known data
    F a man and a woman walk on a surface horizontally and create an 80° angle and 1000N ground reaction force on their leg. If the friction coefficient of the carpet is μ=0.55, and friction coefficient of a tiled floor, μ=0.18 will they slip? Show working to your answer. Can someone please help me with this many thanks!

    2. Relevant equations
    Will they slip? prove your answer.



    3. The attempt at a solution
    mgsin(80)=1000N
    Ff=μN
    1000x0.55
    Ff=550N


    second: mgsin(80)=1000
    1000x0.18

    =180N

    There is less friction on the tiled floor therefore the person walking on it will slip.

    Have you drawn a force diagram?

    Yes l have. The diagram l drew shows a force of 1000N being exerted diagonal against the floor, but i'm not 100% convinced this is the solution.
