Chapter 3, Problem 1OQ
In which of the following situations is the moving object appropriately modeled as a projectile? Choose all correct answers. (a) A shoe is tossed in an arbitrary direction. (b) A jet airplane crosses the sky with its engines thrusting the plane forward. (c) A rocket leaves the launch pad. (d) A rocket moves through the sky, at much less than the speed of sound, after its fuel has been used up. (e) A diver throws a stone under water.
Expert Solution & Answer
To determine
Choose and explain the correct following situation for moving the object appropriately modeled as a projectile.
Answer to Problem 1OQ
The correct option are (a) and (d).
Explanation of Solution
Option (a) is correct. A tossed shoe is moving as a projectile.
Option (b) is wrong. Because, the engine of that jet exhaust exerts force on it.
Option (c) is wrong. A rocket follows the newton third law of motion.
Option (d) is correct. After used the fuel, the rocket follows the newton first law of motion.
Option (e) is wrong. The motion of the stone is act as a projectile.
Conclusion:
Therefore, thecorrect option are (a) and (d).

- 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.
