Lake Point Tower in Chicago is the tallest apartment building in the United States (although not the tallest building in which there are apartments).Suppose you take the elevator from street level to the roof of the building.The elevator moves almost the entire distance at constant speed,so that it does 1.15 ×105J ofwork on you as it lifts the entire distance.Ifyour mass is 60.0 kg,how tall is the building? Ignore the effects offriction.

m g H = 1.15*10^5 J

m = 60 kg
g = 9.8 m/s^2
Solve for H, which will be in meters
