A water-skier with a mass of 68 kg is pulled with a constant force of 870 N by a speedboat. A wave launches him in such a way that he is temporarily airborne while still being pulled by the boat, as shown in the image below. Assuming that air resistance can be ignored, what is the vertical acceleration that the water-skier experiences on his return to the water surface? (Recall that g = 9.8 m/s2)
A. -13.6 m/s2
B. -17.1 m/s2
c. -22.5 m/s2
D. -9.8 m/s2

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.
