Ryugyong+Hotel,+A+Lesserson



The Ryugyong Hotel is a 105-story skyscraper in Pyongyang, North Korea. It is also referred to as the "105 Building" because of its number of stories. The construction of the hotel began in 1987, and had planned on being finished in 1989, but due to numerous delays, construction was halted in 1992. The building of the hotel resumed in 2008, and the exterior of the building was finally completed in 2011. The interior of the hotel is still being built. At a height of 1,080 ft, the Ryugyong Hotel is by far the largest structure in North Korea. It is the world's 40th tallest building and has the 4th highest number of floors. It is the prominent feature of North Korea's skyline.


 * Problem #1:** My family and I are standing on top of the Ryugyong Hotel and are planning to jump off of it. While standing on the top of the building, we are all putting on our parachutes, preparing to jump off. However, before my brother can get the parachute out of the bag, he drops it. Approximately how long does it take to hit the ground?


 * Problem #2:** While everyone is panicking over my brother dropping his parachute, I volunteer to go down and get it. So I go back inside the building, go down the elevator all the way to the lobby, and right as I reach the doors leading outside, I coincidentally see a canon randomly sitting in the lobby by the door. I drag the catapult outside, and put my brother's parachute inside of it. I launch up the parachute with an initial velocity of 300 ft/sec and my brother catches it on top of the building. Approximately how long does it take for my brother to catch it?
