    Dynamics-Coefficients of Kinetic friction

    If the two forces are not equal then that means that the object moves. But knowing that, I still don't know what I'm suppposed to do ...

    Dynamics-Coefficients of Kinetic friction

    Well for part a) I set the forces equal to each other only because I was using the equation Fk=Uk |Fn| as base to which I substituted values until I received a suitable equation. For part b), I'm not too sure what would be different about the forces. The question says that the student is...

    Applied horizontal force homework

    Thank you for replying, but I think I already got the answer. For part a) I used the F=ma formula and rearranged it, added the weights and added the known values into the equation. For part b) I used the same equation as part a) using acceleration from part a) and then to find the total force I...

    Dynamics-Coefficients of Kinetic friction

    Homework Statement A student is pushing horizontally on a table (m=16 kg) to move it across a horizontal floor. The coefficient of kinetic friction between the table and the floor is 0.61. a) Determine the magnitude of the applied force needed to keep the table moving at constant velocity...

    Applied horizontal force homework

    Homework Statement Two veggieburger patties, in contact with each other, are being pushed across a grill. The masses of the burgers are 113 g and 139 g. Friction is negligible. The applied horizontal force of magnitude 5.38x10^-2 N is exerted on the more massiv burger. Determine a) the...
