12kg box of fruit needs to be moved to the other side of the warehouse. (a) Calculate the minimum force required to get the box moving if Ms = 0.47?

Calculate the heat capacity per object when the total energy is 4 quanta. (think of this in terms of increasing from 3.5 quanta of energy in the system to 4.5 quanta of energy in the system, if that were possible.) c4 = __ j/k/object

Using the work energy theorem. what is the velocity of a 850kg car after starting at rest when 13,000j of work is done to it.
