The explanation of this constancy in the rotational velocity is that the distribution of stars in the galaxy lies between high concentration towards the centre and uniform distribution.

standards. Only 1.8% of the stars have projected rotational velocities larger than 300 km s-1 and 0.2% have V sin i larger than 350 km s-1. The mean projected rotational velocity is only 25% of ...

Translational and rotational head acceleration, neck responses, and jaw pressure distribution were measured. High speed video recorded each blow and was used to determine punch velocity. Equilibrium ...
