Central+Plaza,+J+Kronenberger

The Central Plaza was the tallest building in Hong Kong until the completion of the Two International Finance Centre at 1,227 ft tall. This building has a pyramidal atrium at the top which remains the world's highest church. It was the second building outside of America to be taller than 1000 feet. There are 39 columns on every normal floor and the colors of the building are light gray, blue, and dark yellow.

Ren and Ariel finally left Bomont and are visiting the world's highest church, when Ariel realizes that she left her bag in the park below. Being a good husband, Ren goes to get the bag and throws it up to her on the top floor with an initial speed of 400 ft/s. How long does it take for the bag to reach her?
 * __Problem #1__**

__**Problem #2**__ As soon as she gets her bag, Ariel realizes Ren threw her the wrong one, so she drops it to give it back to him. If she dropped the bag from the top of the building, how long will it take to get back to Ren?
