A box is put on a scale which is adjested to read zero , when the box is empty . Astream of pebbles is then poured into the box from a height h above its bottom at a rate of n pebbles . Each pebble has a mass m if the pebbles collide with the box such that they immediately come to rest after collision, find the scale reading at time t after the pebbles begin to fill the box .
