363593 An average force of \(125\;N\) is applied on a machine gun firing bullets each of mass \(10\;g\) at the speed of \(250\;m{\rm{/}}s\) to keep it in position. The number of bullets fired per second by the machine gun is

363594 A rocket of mass 4000 \(kg\) is set for vertical firing. How much gas must be ejected per second so that the rocket may have initial upward acceleration of magnitude \(19.6\,m/{s^2}\)? [Exhaust speed of fuel \( = 980\,m/s\)]

363595 A rocket of initial mass 1500 \(kg\) ejects gas at a constant rate of 10 \(kg\)/\(s\) with a relative speed of 5 \(km\)/\(s\). What is the acceleration of the rocket 50 seconds after the launch, neglecting gravity?

363596 A stream of glass beads, each with a mass of \(15\,g\), comes out of a horizontal tube at a rate of 100 per second. The beads fall a distance of \(5\,m\) to a balance pan and bounce back to their original height. How much mass must be placed in the other pan of the balance to keep the pointer at zero?
