A97 kg man holding a 0.365 kg ball stands on a frozen pond next to a wall. he throws the ball at the wall with a speed of 11.3 m/s (relative to the ground) and then catches the ball after it rebounds from the wall. how fast is he moving after he catches the ball? ignore the projectile motion of the ball, and assume that it loses no energy in its collision with the wall.

The field lines around one end of a bar magnet are shown below based on the diagram, what can you conclude about the pole of the magnet? a.is a south pole because the field hnes spread out from this end b.a north pole because the field lines spread out from this end c.a nouth pole because the field lines enter the magnet at this end d.is a north pole because the field lines enter the magnet at this end
