If the maximum possible exhaust velocity of a rocket be `2km//s` calculate the ratio `m_(0)//m` for it to acquire a veocity of `11.2km//s` after starting from rest .

Calculate the ratio m_(0)//m for a rocket to attain the escape velocity of 11.2km s^(-1) after starting from rest, when maximum exhaust velocity of gases is 1.6km//s .

A rocket of mass 20kg has 180kg fuel. The exhaust velocity of the fuel is 1.6km//s . Calculate the minimum rate of consumption of fuel so that the rocket may rise from the ground. Also, calculate the ultimate vertical speed gained by the rocket when the rate of consumption of fuel is (g=9.8m//s^2) (i) 2kg//s (ii) 20kg//s
