Question

An 95.0 kg spacewalking astronaut pushes off a 660 kg satellite, exerting a 90.0 N force for the 0.490 s it takes him to straighten his arms.

How far apart are the astronaut and the satellite after 1.30 min ?

Answer #1

An 82.0 kg spacewalking astronaut pushes off a 655 kg satellite,
exerting a 95.0 N force for the 0.540 s it takes him to straighten
his arms. Part A How far apart are the astronaut and the satellite
after 1.30 min?

An 91.0 kg spacewalking astronaut pushes off a 640 kg satellite,
exerting a 85.0 N force for the 0.450 s it takes him to straighten
his arms.
How far apart are the astronaut and the satellite after 1.10 min
?
Express your answer with the appropriate units.
I got 33.6 m, but its not accepting the anser.

An astronaut is on a 150 m life-line circling the
spaceship at two revolutions per min. The line is shortened until
his speed reaches 40 m/s. How long is the life-line at that time
(in m)? (Assume the momentum of inertia of the astronaut is
mr2 and think conservation of angular
momentum.)
A car with a mass of 1200 kg is traveling at 17 m/s. The
driver applies the brakes which provide a frictional force of 7000
N to stop...

A 110 kg astronaut (including space suit) acquires a speed of
2.35 m/s by pushing off with his legs from a 2000 kg space
capsule.
(a)
What is the change in speed of the space capsule?
Express your answer with the appropriate units.
(b)
If the push lasts ttt = 0.525 ss , what is the average force
exerted by each on the other? As the reference frame, use the
position of the capsule before the push.
Express your answer...

You sign up for a bungee jump off a tall bridge. A thick rope
with a fixed length of 24.0 m is tied to the bridge, and a bungee
cord with an unstretched length of 10.0 m is then connected to the
rope. The other end of the bungee cord is attached to your
legs.
You step off the bridge, falling from rest. The bungee cord does
not start exerting any force on you until you have fallen a
distance...

Please answer all not understanding:
1. Volumetric expansion coefficients of simple materials are
often well catalogued. However, the thermal expansion coefficient β
of a human body is less well known. This could affect the human
body\'s specific gravity and, therefore, measurements of its
body/fat ratio. Suppose that a human body of weight w0 (on dry
land) is placed on a scale while completely immersed in
formaldehyde of temperature T1. Once the temperature increases by
ΔT, the scale reading drops by...
