An 77.0 kg spacewalking astronaut pushes off a 645 kg satellite, exerting a 85.0 N force for the 0.500 s it takes him to straighten his arms.
How far apart are the astronaut and the satellite after 1.30 min ?
Sol::
Given
Msat= 645 kg
Mas=77 kg
F= 85 N
t=0.5 s
Now using conservation of linear momentum,
F_action = (M_sat) Δv/Δt
85 = (645)(v - 0)/0.5
v = 0.0658 m/s
F_reaction = -(M_ast) Δv/Δt
85 = -(77)(V - 0)/0.5
V = -0.552 m/s
relative velocity satellite with respect to astronaut is,
ΔV = v - V
ΔV = 0.0658 - (-0.552)
ΔV = 0.6178 m/s
s = ΔV t
s = 0.6178* (1.3 * 60)
s = 48.188 m
s =48.2 m
Hope this helps and will get RATED

Question # 1 An 87.0 kg spacewalking astronaut pushes off a 640 kg satellite, exerting a 115 N force for the 0.590 s it takes him to straighten his arms. How far apart are the astronaut and the satellite after 1.20 min ? Question # 2 It is proposed that future space stations create an artificial gravity by rotating. Suppose a space station is constructed as a 1200-m-diameter cylinder that rotates about its axis. The inside surface is the deck...
