In a flour mill wheat to be milled is elevated 15m to the top of the building. Neglecting friction (a) how much work is accomplished in elevating 1t of wheat to the top of the mill?

(b) What is the potential energy of 1t of wheat located at the top of the mill? (c) what is the velocity of the wheat when it strikes the ground floor? (d) Neglecting friction, what is the kinetic energy of 1t of wheat just before it strikes the ground floor of the mill when allowed to fall freely in a tub from the top of the ground floor of the flour mill?
