Kinematics: motion on a slope

  1. Jan 25, 2017 #1
    1. The problem statement, all variables and given/known data
    You are sliding downhill a slope of 10% (what angle is that?). Calculate how the starting velocity of 10 km/h changes within the first 120 s. After that you try to climb up an icy hill with 5% slope. Is that possible?

    2. Relevant equations
    Vf = Vi +At

    3. The attempt at a solution
    I tried to put acceleration as -9.81 and using the kinematic formula Vf = Vi +At but the result was way too big. Should I take those 5.71 degrees and do something with them?

    Like %100 slope is 90 degree %0 slope is 0 degree so %10 is ??

    Try to calculate the acceleration that you ll gain in inclined plane

    How should I do this I if Ii don't have the mass?

    You dont need mass If you write down the equations you'll see

    Try To write down the total force acting on the object.Then you fill find a

    Well I really don't know wich eccuations are you talking about.

    Do you know Newton's Law and their applications ?
