Velocity and Displacement with uniform acceleration 1. A car with an initial speed of 13.7 m/s accelerates at a uniform rate of 0.92 m/s2 for 3.6 s. Find
the final speed and displacement of the car during this time.

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?
