1. An astronaut in her space suit has a total mass of 87 kg, including her suit and oxygen
tank. Her tether line loses its attachment to her spacecraft while she's on a space walk.
Initially at rest with respect to her spacecraft, she throws her 12 kg oxygen tank away
from herself with a speed of 8 m/s to propel herself back towards it. Determine her
velocity as she moves back towards the spacecraft. (use conservation of momentum)
2. A dentist's drill starts from rest. After 3.2 s of constant angular acceleration, it turns at a
rate of 2,628 rad/s. Find the drills angular acceleration

Expert Solution

Step 1

Note: As per the guidelines, we can only answer first question of multiple question. Sorry for the inconvenience. For answer to the other question attached here, kindly re-post the question with mentioning the unanswered question part.

Given data:

Total mass (mass of astronaut + mass of tank), $m_{AT} = 87 kg$
Initially, she is at rest. That means, the velocity of the astronaut and tank is equal to zero.
Mass of oxygen tank, $m_{T} = 12 kg$
The velocity with which she throws the tank is 8 m/s

Our question is to find the final velocity of the astronaut.
