Aspeedboat starts from rest and accelerates at - 2.01 m/s2 for 7.00 s. at the end of this time, the boat continues for an additional 6.00 s with an acceleration of +0.518 following this, the boat accelerates at 1.49 m/s2 for 8.00 s (a) what is the velocity of the boat at t = 21.0 s? (b) find the total displacement of the boat.

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.
