The equation of motion for a particle moving along the y-axis is given as y(t) = 3t2 - 6t + 2 for t2 0. Part A: Find the velocity and acceleration functions. (10 points)
Part B: Describe where the particle changes direction and the intervals where the particle speeds up or slows down. (20

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
