    Angles Projectile
Click For Summary
To solve the projectile problem, it is essential to recognize that the projectile is fired horizontally, meaning the launch angle is 0 degrees. The key to determining how long the projectile remains in the air lies in calculating the time it takes to fall 53.0 meters under the influence of gravity. Using the formula for free fall, the time can be calculated as approximately 3.3 seconds. The horizontal velocity does not affect the time of flight, which is solely determined by the vertical distance and gravitational acceleration. Understanding that the angle is effectively zero simplifies the approach to solving the problem.

A projectile is fired horizontally from a gun that is 53.0 m above flat ground. The muzzle velocity is 235 m/s. How long does the projectile remain in the air?

All of the practice problems in my book are given an angle to work with. For some reason I'm having a hard time starting this problem because I'm under the impression that I need to find an angle but I feel like I don't have enough information. Any help to point me in the right direction is greatly appreciated.

you still have an initial angle. It is just 0 degrees from the horizontal axis.
 
Which means it is falling out of "rest" downwards.

Thread 'Correct statement about size of wire to produce larger extension'

The answer is (B) but I don't really understand why. Based on formula of Young Modulus: $$x=\frac{FL}{AE}$$ The second wire made of the same material so it means they have same Young Modulus. Larger extension means larger value of ##x## so to get larger value of ##x## we can increase ##F## and ##L## and decrease ##A## I am not sure whether there is change in ##F## for first and second wire so I will just assume ##F## does not change. It leaves (B) and (C) as possible options so why is (C)...
