A stream of glass beads, each with a mass of 15 gram, comes out of horizontal tube at a rate of 100 per second. The beads fall a vertical distance of 5 m to a balance pan and bounce back to their original height. How much mass (in kg) must be placed in the other pan of the balance to keep the pointer at zero? (take $g=10\mathrm{m}/{\sec }^2$ )
