While at rest during a spacewalk, an astronaut is 11 m from an entrance to the space station. To reach the entrance, she faces away from the entrance and throws a 0.500 kg wrench directly in front of her at a speed of 25.3 m/s. The astronaut and her space suit have a combined mass of 115 kg.

1. 1. What is the astronaut's momentum and speed after the throw? 
2. 2. How long will it take the astronaut to travel the 11 m to the space station?
