372212 A bullet is fired from a gun. The force on the bullet is given by $F=600-2\times {10}^{5}t$, where $F$ is in Newton and $t$ in second. The force on the bullet becomes zero as soon as it leaves the barrel. What is the average impulse imparted to the bullet?

372213 A rocket of mass $1000\mathrm{kg}$ is to be projected vertically upwards. The gases are exhausted vertically downwards with velocity $100{\mathrm{ms}}^{-1}$ with respect to the rocket. What is the minimum rate of burning of fuel, so as to just lift the rocket upwards of fuel, so as to just lift the rocket upwards against, the gravitational attraction? (Take $g=10{\mathrm{ms}}^{-2}$ )
