A commercial Boeing 737-800 airplane could seat 160 passengers. It takes off with to weight of 175,000 lbs from the Phoenix airport and eventually achieves its cruising spe of 550 mph (miles per hour) at an altitude of 30,000 ft. For g = 9.78 m/s², determine change in kinetic energy and change in potential energy for the airplane, each in kJ. Ple convert the English unit to Sl unit first for each physical quantity.

1) A small steel block and a magnet rest on a horizontal frictionless table. The steel block weighs 0.07N and the magnet is fixed to the table. The force acting on the steel block by the magnet is inversely proportional to the square of the distance between the steel block and the magnet. When the block is 26cm away from the magnet, the force becomes 0.145N. If the block starts its motion from rest at this position, what is the magnitude of the velocity of the block when it is 9.5cm away from the magnet?
