You are piloting a helicopter which is rising vertically at a uniform velocity of 14.70 m/s. when you reach 196.00 m, you see barney. you project a banana with a horizontal velocity of 8.50 m/s from the rising helicopter, with the mean intent to get barney. when does the banana reach barney's head, if he is 1.70m tall?

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.
