You are walking down a straight path in a park and notice there is another person walking some distance ahead of you. the distance between the two of you remains the same, so you deduce that you are walking at the same speed of 1.13 m/s.1.13 m/s. suddenly, you notice a wallet on the ground. you pick it up and realize it belongs to the person in front of you. to catch up, you start running at a speed of 2.85 m/s.2.85 m/s. it takes you 14.5 s14.5 s to catch up and deliver the lost wallet. how far ahead of you was this person when you started running?

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.
