A rocket of mass `40kg` has `160kg` fuel. The exhaust velocity of the fuel is `2.0km//s`. The rate of consumption of fuel is `4kg//s`. Calculate the ultimate vertical speed gained by the rocket. `(g=10m//s^2)`

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

The force on a rocket moving with a veloctiy 300 m/s is 210N. The rate of consumption of fuel of rocket is

The force on a rocket moving with a veloctiy 300 m/s is 210N. The rate of consumption of fuel of rocket is

The force on a rocket moving with a veloctiy 300 m/s is 210N. The rate of consumption of fuel of rocket is

In the previous problem , if the mass of fuel is 5000 kg and the rate of fuel consumption is 50 kg//s , find the speed acquired by the rocket when all fuel is consumed .
