t=rF sin(0) 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)

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
