An astronaut in outer space holds a 2.0 kg wrench in their hand. The astronaut and the wrench are initially at rest with respect to one another. The wrench is then thrown (ignoring any rotational effects) and an observing astronaut measures each body’s velocity following the throw. The wrench moves with a velocity of +8.0 m/s while the astronaut moves at -0.15 m/s. Calculate the mass of the astronaut.
