sand discharge speed from a conveyor belt

    • Sand drops on a conveyor belt at constant rate

    2021-1-9  If in 1 second, sand with mass m has fallen on the belt and accelerated to speed v, then the sand has gained kinetic energy $$E_K=\frac{1}{2} m v^2$$. As the mark scheme does confirm this is the amount of energy gained by sand, it states that this cannot be the only energy involved here, otherwise the acceleration of a grain of sand will be infinitely large.
