Pushy Astronaut(adsbygoogle = window.adsbygoogle || []).push({});

--------------------------------------------------------------------------------

a) An astronaut of mass 70 kg pushes off a satellite of mass 420 kg, exerting a force of 120 N for the 0.83 s they are in contact. What is the speed of the astronaut after they have separated?

vastronaut = m/s

HELP: Remember Newton's Third Law. The astronaut exerts a force on the satellite. What is the force that the satellite exerts on the astronaut?

HELP: Apply F = ma. You can figure out the force from the Third Law. You know the mass so you can find the acceleration. Once you know that, apply kinematics to find the speed.

b) What is the speed of the satellite after they have separated?

vsatellite = m/s

--------------------------------------------------------------------------------

c) How far apart are they after 1 minute?

D= m

I request some intial help with these parts thanks,
