1.	A rocket vurns 50g of fuel per secondejecting it as a gas with a velocity of 5xx10^(5) cm s^(-1). What force is exerted by the gas on the rocket?
Answer» Solution :We are to CALCULATE the upward thurst on the rocket. Upword THRUST `=v_(r)(Deltam)/(Deltat), Now , (Deltam)/(Deltat)=50 gs^(-1)` `v_(r)=5XX10^(5) cms^(-1)` `:."upwards thrust"= 5xx10^(5) cm s^(-1)xx50 gs^(-1)=250xx10^(5) ` dyne=250N
