__The US Bank Tower__
Alternatively titled the Library Tower or the First Interstate World Center, the US Bank Tower resides within Los Angeles, California. When the building was completed it became the tallest building on the Pacific coast with a height of 1018.01 ft. The building was designed, due to it's location, to withstand earthquakes up to 8.3 on the Richter scale. Along with being the tallest building on the Pacific coast the building is also the tallest in the United States west of the Mississippi river.

Height: 1018.01 ft Problem #1 A helicopter carrying Michelle and Barack Obama is landing atop the US Bank Tower. As the helicopter is landing one of the secret service agents answers a call and ends up dropping his phone. His phone flies out of the helicopter and off the edge of the building. How long will it take for the phone to fall to the ground? Problem #2 The phone miraculously landed safely in the bag of a woman walking along the sidewalk. She looks up to the top of the building wondering where the phone came from and tries with all her strength to throw it back at the top of the building. She realizes she can't throw with her strength so she finds a canon that can shoot the phone upwards with a speed of 523 ft/sec. How long does it take the phone to reach the top of the building?
