... for the position. Rewrite this equation in terms of the velocity and solve for ~v (t). Does your solution give the correct result for t → ∞? What is the physical meaning of this asymptotic value? Would you expect the time during which the ball rises to be longer or shorter than the time during which ...

Accreting millisecond X-ray pulsars, from accretion disk to magnetic
... Moreover, neutron stars can rotate at spin periods near a millisecond, with surface velocities as high as several percent of the speed of light. Finally, neutron stars have magnetic fields which are among the strongest observed in the Universe: typical values range from B ∼ 108 Gauss for very old sy ...
