A 140 kg astronaut (including space suit) acquires a speed of 2.56 m/s by pushing off with his legs from a 1730 kg space capsule. The change in speed of the space capsule is .207 m/s.
How would I find the change of momentum in the motion from above?
m1 = 140 kg astronaut
m2 = 1730 kg space capsule
v1 initial = astronaut 0
v2 initial = space capsule 0
v1 final = astronaut 2.56 m/s
v2 final = space capsule .207 m/s
would the change of momentum equal the following?
J (impulse)= pfinal - pinital
Momentum of Final...---------------------------------------------------
p1 = astronaut m1 x v1 final
140 x 2.56
358.4
p2 = space capsule m2 x v2 final
1730 x .207
358.11
pfinal about = 358
Momentum Initial --------------------------------------------------------
If i solved for the momentum using v1 inital and v2 inital then the momentum of both would be 0.
Pinitial = 0
Pf = 358
Pi = 0
J = 358 - 0
J = 358
Would 358 be the change of momentum in the motion above?
Does momentum have units?
Momentum is a vector quantity so therefore no units?
