a spaceship is moving at 1000 m/s release a satellite of mass 1000 kg at a speed of 10 000 m/s. what is the mass of the spaceship if it slows down to a velocity of 910 m/s?
Answered by Damon
initial momentum = 1000 m

final momentum = 910(m-1,000) + 10^7

90 m = .091*10^7 + 10^7 = 1.091*10^7
m = 121,222 kg

if 1000m/s was the speed of the spaceship and after the release the released object is traveling 10000m/s with mass of 1000kg so this implies
910m/s=x
10000m/s=1000kg
x=910*1000/10000
x=91kg
