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).
