1. The problem statement, all variables and given/known data Find the final velocity of a 5g steel ball bearing being pulled by a neodymium magnet with a pull force of 6.1 pounds (27.1 Newtons) in a straight line on a frictionless surface after being pulled for .1 meters 2. Relevant equations F=MA 3. The attempt at a solution f=ma 27.1 = .05a a = 542m/s^2 The bearing travels for .1 meters, which is 1.85E-4 as far as it will travel in the first second (if the above solution for acceleration is correct), so t must be 1.85E-4 seconds. v = (.1 m)/(1.85E-4 s) = 542m/s As you can probably see by how unrealistic the numbers I came up with are, I'm not sure what to do. Could you maybe think about this in terms of kinetic energy? I gotta feeling that this problem is more complicated than I initially thought.
