A rocket traveling through space with a constant velocity of 10m/s^2 fires up a booster. The booster accelerates the rocket at a rate of 5m/s^2. What distance in meters has the rocket traveled within 12 seconds after the booster is turned on?

Ametal ring 4.20 cm in diameter is placed between the north and south poles of large magnets with the plane of its area perpendicular to the magnetic field. these magnets produce an initial uniform field of 1.12 t between them but are gradually pulled apart, causing this field to remain uniform but decrease steadily at 0.240 t/s . (a) what is the magnitude of the electric field induced in the ring? (b) in which direction (clockwise or counterclockwise) does the current flow as viewed by someone on the south pole of the magnet?
