A brass (nonmagnetic) block A and a steel magnet B are in equilibrium in a brass tube under the magnetic repelling force of another steel magnet C located at a distance x=.004 m from B. The force is inversely proportional to the square of the distance between B and C. If block A is suddenly removed, the acceleration of block B is a = -9.81 + (k/(x^2)) where a and x are expressed in m/s^2 and meters respectively, and k = 4 e -4 m^3/s^2. Determine the max velocity and acceleration of B Please leave answers in m or mm.
