A bullet with a mass is fired horizontally into a block of mass which is initially at rest on a horizontal surface. The bullet passes through the block, emerging from the other wise with a speed of . There is a coefficient of kinetic friction of between the block and the surface. The block is observed to come to rest after traveling a distance along the surface. What was the initial speed of the bullet

Dao makes a table to identify the variables used in the equations for centripetal acceleration. what quantities belong in cells x and y?

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?
