lake point tower in chicago is the tallest apartment biulding in the united states (although not the tallest biulding in which there are apartments). supose you take the elevator from street level to the roof of the biulding. the elevator moves almost the entire distance at constant speed, so that it does 1.15 x 10^5J of work on you as it lifts the entire distance. if your mass is 60.0 kg, how tall is the building? ignore the effects of friction.

can someone please help with the steps in how to do it ?
