    Calculate the coefficient of kinetic friction for the mass on the surface

    I have read, and I don't understand, also I'm tired and I have less than 6 hours to finish the exercises because their due date is at 7:00 am and I need to sleep because I have my physics test tomorrow and arildno was rude to me and I don't know how I can do that exercise, was trying with...

    Calculate the coefficient of kinetic friction for the mass on the surface

    ok, I didn't come here for you to insult me, I don't understand what I have to do, I'm not very good at physics right now I just want you to help me, explain me, because my proffesor doesn't explain the exercises, not do my homework but you know what, I'm really tired cause I took a test...

    Calculate the coefficient of kinetic friction for the mass on the surface

    I need help with a physics problem, if someone could help me with the fomula, please. When mass M is at the position shown, it is sliding down the inclined part of a slide at a speed of 2.23 m/s. The mass stops a distance S2 = 1.85 m along the level part of the slide. The distance S1 =...

    Help with Forces: Calculate Horizontal Stopping Force

    I don't know how is exactly that formula, but I find one, maybe it's the same. F=m*a a= (v^2-v_{i}^2)/(2* \Delta x) Now I have other problem Find the stopping distance of that same car when it is traveling up a 19.9° slope, and it locks its wheels while traveling at 33.5 m/s...
