Now we are going to look at a classic example of projectile motion: a bullet fired from a gun. A paintball is fired horizontally at a speed of 75.0 m/s from a point 1.50 m above the ground. The ball misses its target and hits the ground some distance away. (a) For how many seconds is the ball in the air? (b) Find the maximum horizontal displacement (which we’ll call the range of the ball). Ignore air resistance.

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?
