a model rocket is made up of a shuttle of mass 20kg, and a fuel tank which has a mass of 4kg when it is empty. when the rocket attains an upwards velocity of 10m. per sec .all of its fuel is used up. At this point ,the empty tank is fired velocity to 13m. per sec .calculate the change in momentum of the rocket without empty fuel tank (60m. per sec upwards)​
