What kinetic energy does the sack have just before it strikes the floor?

-a 98.0 n sack of grain is hoisted to a storage room 50.0 m above the ground floor of a grain elevator. the rope being used to lift the sack of grain breaks just as the sack reaches the storage room.

When an object is at any height above the ground, it has gravitational potential energy. If the object falls, it loses this gravitational potential energy and this energy is converted to kinetic energy. By this logic, we can say:

Gravitational potential energy of grain sack = Kinetic energy of grain sack

GPE = mgh
        = (mg) x h
        = 98.0 x 50.0
        = 4,900 J

When the volume of the actual gas is greater than the volume predicted by the law of idea gas. The explanation that the law of ideal gas does not include a factor for molecular is Volume because of the fact at temps larger than the temp of the gas will liquify, the attraction of the molecules and at low stress the molecular will be ignored. Under the circumstances above the gas equation is a sturdy approximixation for the habit of a real gas. and yet at extreme stress, low temps or the two you should make corrections for molecular quantity and molecular factors of interest.
