Part 1: A magnetic levitation or maglev train rides rails without touching them. Explain how this works using your data. Include the appropriate magnet drawing in your answer. Part 2: Two objects are near a bar magnet. One is about 1 cm away, while the other is 6 cm away. Compare and contrast the magnetic force that affects each object. Use your data to answer the question

Amachinist turns the power on to a grinding wheel, at rest, at time t = 0 s. the wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 96 rad/s. the wheel is run at that angular velocity for 40 s and then power is shut off. the wheel slows down uniformly at 1.5 rad/s2 until the wheel stops. in this situation, the time interval of deceleration is closest to:
