A ball is projected with a horizontal velocity of 1.1m/s from point A at the edge. The ball lands at point B from the base of the table. Calculate i. Time table taken for ball to fall from A to B ii. Determine the height of the table iii. If the mass of the ball is increases and ignoring air resistance, compare the time taken of the second ball with the time taken for that in question (i) and explain your answer.

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.
