A space vehicle is traveling at 4750 km/h relative to the Earth when the exhausted rocket motor (mass 4m) is disengaged and sent backward with a speed of 81 km/h relative to the command module (mass m). What is the speed of the command module relative to Earth just after the separation? km/h
Homework Answers
Then according to the law of conservation of linear momentum
MU = (M-m)V + mv
Also we are given that M= 5, m=4 , (M-m)=1 , U= 4750km/h, (V-v)= 81km/h. then the equation becomes
(5*4750) = V + 4(V-81)
then V= 4764.8

A rocket traveling 1950 m/s away from the Earth at an altitude of 6400 km fires its rockets, which eject gas at a speed of 1300 m/s (relative to the rocket). If the mass of the rocket at this moment is 2.65×104 kg and an acceleration of 1.6 m/s2 is desired, at what rate must the gases be ejected? The answer is not 132.19 it is coming up wrong.
