A steel ball with mass 40.0 g is dropped from a height of 2.00 m onto a horizontal steel slab. The ball rebounds to a height of 1.60 m. (a) Calculate the impulse delivered to the ball during impact. (b) If the ball is in contact with the slab for 2.00 ms, find the average force on the ball during impact.
PHYS 1010 Notes Week 8 February 29 Jan 4 Magnetic fields Magnetic particles are dipoles, and the two poles of a magnet are the North and South poles All magnetic field lines originate from the North Pole and move toward the South Pole We draw magnetic field lines by placing a compass near the magnet and tracing the direction in which the arrow of the compass points (towards the south magnetic pole) Right now the south magnetic pole is at the North Pole of the Earth Earth's poles have switched historically Earth's magnetic poles are not exactly located at the north and South Pole Field lines pass through the magnet and form closed loops Opposite magnetic poles attract each oth
