http://stackoverflow.com/questions/11257462/how-do-i-apply-a-force-to-a-body-in-the-direction-it-is-traveling-box2d

And now the tricky part I calculated the x and y velocities vx and vy respectively and used these to calculate the resultant velocity vr and the angle that they were traveling in t . If vr is less than the velocity I want destroyerVelocity then.. than the destroyerVelocity. This was done in the same manner just with an opposite force. Run a log statement of the resultant velocity with the destroyerVelocity being 7 and it reads something like 6.900001 6.9995001 7.00028 7.13005 ... Although..
