    Finding Coefficient of Kinetic Friction

    Homework Statement See, I was collecting data for a lab, and now when I look it at, I'm being asked to find the kinetic friction force and the coefficient of friction. What I was given was: the mass of the block: .261 kg gravity: 9.81 m/s2 the acceleration: -7.3125 m/s2 And that's it. If it...

    Kinematics Question

    Homework Statement Given v0=0 m/s, x0=0 m, and t=10 s, use all three kinematic equations together to find xf. Homework Equations vf=v0+at xf=x0+v0t+1/2at2 vf2=v02+2a(xf-x0) The Attempt at a Solution The more I look at this, the less sense it makes. First off, I tried to plug the values into the...
