1. 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...
2. Accelerating projectile force needed

There is no attempt at a solution.
3. Kinematics Question

Thanks for all the help! :)
4. Kinematics Question

If that were the case, then it wouldn't require all three equations would it? Just the second one, no?
5. Kinematics Question

Nothing else is stated other than what is provided. It's actually a problem from a summer assignment that is due the first day of the semester. There's no other information in the header, as it just provides a brief overview of instructions for the section, which is "Algebra", and it basically...
6. 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...
