You are an engineer in charge of designing a new generation of elevators for a prospective upgrade to the empire state building. before the state legislature votes on funding for the project, they would like you to prepare a report on the benefits of upgrading the elevators. one of the numbers that they have requested is the time it will take the elevator to go from the ground floor to the 102nd floor observatory. they are unlikely to approve the project unless the new elevators make the trip much faster than the old elevators. if state law mandates that elevators cannot accelerate more than 4.20 m/s2 or travel faster than 19.3 m/s, what is the minimum time in which an elevator can travel the 373 m from the ground floor to the observatory floor?

b. more people end up in u. s. emergency rooms because of fall-related injuries than from any other cause. at what speed vwould someone hit the ground who accidentally steps off the top rung of a 12.00 ft tall stepladder? (that step is usually embossed with the phrase "warning! do not stand on this step.") ignore the effects of air resistance. let the +y direction point vertically upward and the origin be on the ground.

b would be the answer

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop

-first use of geothermal energy occurred more than 10,000 years ago in north america by american paleo-indians

-the first industrial use of geothermal energy began near pisa, italy in late 18th century

-in 1904, italian scientist piero ginori conti invented the first geothermal electric power plant in which steam was used to generate the power

-with the above experiment, the first geothermal plant in usa started in 1922 with a capacity of 250 kilowatts

-however, in 1946 first ground-source geothermal heat pump installed at commonwealth building in portland, oregon

-during the 1960’s, pacific gas and electric began operation of first large scale geothermal power plant in san francisco, producing 11 megawatts

-in 1973, when oil crisis began many countries began looking for renewable energy sources and by 1980’s geothermal heat pumps (ghp) started gaining popularity in order to reduce heating and cooling costs

-as effect of climate change started showing results, governments of various countries joined hands to fight against it, for which kyoto protocol was signed in japan in 1997, laid out emission targets for rich countries and required that they transfer funds and technology to developing countries, 184 countries have ratified it

hope this
