A particle moves on the x axis under the influence of the force F = ?/x3. The initial position is x0, and the initial velocity is 0. [Data: mass = 1 kg; ? = 2 N m3; x0 = 3 m. ](A) Determine the final velocity.(B) Determine the position where the velocity is 50 percent of the final velocity.(C) Determine the time when the velocity is 50 percent of the final velocity.
