Answer:
velocity is 5 m/s
Explanation:
mass of astronaut (M)=100kg
mass of object (m)=10kg
Initially they are rest , so initial velocity (u)= 0 m/s
Final velocity of object ;
let final velocity of astronaut = (Unknown)
Now , By conservation of linear momentum
Initial momentum = Final momentum
Now insert values
Further simplifying
So,
So, velocity is 5 m/s (the negative sign is due to direction)
