A box is put on a scale that is adjusted to read zero when the box is empty. A stream of marbles is then poured into the box from a height h above its bottom at a rate of R (marbles per second). Each marble has a mass m. The collisions are completely inelastic; assume that the marbles stick to the box without bouncing when they hit. Find the scale reading of weight at time t after the marbles begin to fill the box. Deter- mine a numerical answer when R = 115 S -l , h = 9.62 m, m = 4.60 g, and t = 6.50 s.
