Find the fractional decrease of kinetic energy of a particle of mass m_1 when a head-on elastic collision takes place with another particle of mass m_2 initially at rest. In this context show why hydrogen would be best to be used for slowing down neutrons. Actually \text{D}_2\text{O}, not \text{H}_2\text{O} is used why?

A rocket of mass 1000\text{ kg} is ready for a vertical take off. The exhaust velocity of its fuel is 4.5\text{ km/s}. Deduce (i) the minimum rate of fuel ejection so that the rocket weight be just balance, (ii) the velocity acquired in 8\text{ s} if the fuel ejection rate is 2.50\text{ kg/s}. (You may neglect the effect of changing mass of the rocket in the given conditions.)

Define Reynold's number, the cross sectional radius of a pipeline decreases following the relation. r = r_0 e^{-ax}, where a = 0.6\text{ m}^{-1}, x is the distance (in \text{m}) from the pipeline inlet. Calculate the ratio of Reynold's number for two cross sections separated by \Delta x = 3\text{m}.
