8. Ron pushes a 7.27-kg bowling ball with a force of 16.5 newtons for 0.522 seconds as he places the ball on the ball rack at the bowling alley. It rolls toward an identical stationary bowling ball
and stops when it makes head-on contact. With what speed does the second ball roll
away on the rack?

Assume that two of the electrons at the negative terminal have attached themselves to a nearby neutral atom. there is now a negative ion with a charge -2e at this terminal. what are the electric potential and electric potential energy of the negative ion relative to the electron? the electric potential and the electric potential energy are both twice as much. the electric potential is twice as much and the electric potential energy is the same. the electric potential is the same and the electric potential energy is twice as much. the electric potential and the electric potential energy are both the same. the electric potential is the same and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron. the electric potential is twice as much and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron.
