Spaceship Malfunction. You and your team get a distress call from another ship indicating that there has been an explosion and their
propulsion and navigation systems are now off line. A large piece of their ship has been jettisoned into space, and their life support
systems are failing. They need help as soon as possible. You try to track them, but are only able to pick up the piece of the craft that had
been projected away from them in the explosion. You look up the make and model of their ship, a Galaxy Explorer 5000 (GE 5000),
which has a total mass of 51000 kg. The piece heading in your direction is the ship's storage module, and has a mass of 8500 kg.
The GE 5000 was at rest with respect to your ship at the time of the explosion.
(a) Assuming you received the distress call 20 minutes before the jettisoned storage module passed by your ship at a speed of 650 m/s,
what is the speed of the damaged craft?
(b) How far away is the Galaxy Explorer 5000 when its storage module passes by?…

- Georgia, standing on the back of the pick-up truck, wants to throw her last piece of balut to her mortal enemy, Emma. before the truck started moving, the two women are separated by a distance of 2 m. For two seconds, the truck uniformly accelerated until it reached a velocity of 4 m/s which it then maintained. With hatred, Georgia throws the last piece of balut with a velocity of 12.5 m/s at an angle of 40° from horizontal, measured relative to the truck. If she makes the throw 2.8 seconds after the truck started moving, will she be able to hit Emma? Note that Emma is at rest due to exhaustion from their earlier fight and she cannot dodge the balut.
