Answer:
Two astronauts, each of mass 75kg, are floating next to each other in space, outside the space shuttle. They push each other through a distance of an arm's length =1m each with a force of 300N.If the final relative velocity of the two, w.r.t each other is V
0
m/s, find the value of
4
(V
0
)
2
( Note that both astronauts are displaced by 1m)
Hard
ANSWER
Work=Force×.Displacement
=300×(1+1)=600N−m, which is converted to kinetic energy.
Thus 2×
2
1
×75×v
2
=600
or,v=
8
m/s
Relative velocity will thus be 2v (because both move with v in opposite direction).Thus,
4
V
o
2
=
(2×
8
)
2
=8
here you have an example...
hopes it helps you....
