Homework Help: Kinetic friction

  1. Apr 30, 2012 #1
    1. The problem statement, all variables and given/known data

    An object of mass m1=50kg, connected to another object of mass m2=20kg by a cable,is driven up an inclineof 30° by a force F , acting on m1 and parallel to the incline. Assuming a coefficient of kinetic of 0.4 between the two objects and the icline:

    1-what should be the magnitude of the applied force to move up the icline with a constant speed of 3 m/s?
    2- What is the tension force in the cable connecting the two objects?

    Hi 5o5a! Welcome to PF.

    You may have missed seeing in the conditions for using this forum that you must show your attempt at solving the problem when you post the question. Otherwise, it reads as though you are expecting someone to do your homework for you, and that is not the purpose of this forum.

    Have you got some working to show for this problem?
