To provide protection to the player, a football helmet receives the initial blow and begins to move, the padding inside the helmet compresses slowly thus slightly delaying the movement of the player's head. the player's head begins to move but accelerates slower than the helmet Impact equals the change in momentum (velocity x mass). The less impact received, the less pain and injury conveyed to the player. Acceleration is the rate at which velocity changes and is proportional (via mass) to momentum. Thus, the lower the , the more protection provided by the helmet and less damage sustained by the player.

Determine el momento angular de un rueda de 3000g moviendose a 10m/s con un radio de giro de 400cm

An isolated conducting spherical shell carries a positive charge. part a which statement (or statements) about the electric field and the electric potential inside and outside the spherical shell is correct? which statement (or statements) about the electric field and the electric potential inside and outside the spherical shell is correct? electric potential inside the shell is constant and outside the shell is changing as 1/r2 both the electric potential and the electric field does change with r inside and outside the spherical shell electric potential inside and outside the shell is constant, but not zero electric potential inside the shell is constant and outside the shell is equal to zero electric field inside and outside the shell is constant (does not change with the position r), but is not equal to zero electric field inside and outside the shell is changing as 1/r (where r is the distance from the center of the sphere) electric field inside is equal to zero and outside the shell is constant, but not zero electric potential inside the shell is constant and outside the shell is changing as 1/r electric field inside and outside the shell is changing as 1/r2 electric field inside is equal to zero and outside the shell is changing as 1/r2 electric field inside and outside the shell is zero electric field inside is constant and outside the shell is changing as 1/r
