Luis rushes 40 m towards his truck. He notices he forgot his shoes and returns back to his house. His total travel time is 60 s. What is luis’s average velocity over the 60 s period? And what is luis’s average sped over the 60 s period?

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?
