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 at greater than 5.10 m/s2 or travel faster than 16.8 m/s, what is the minimum time in which an elevator can travel the 373 m from the ground floor to the observatory floor?

Two loudspeakers, 5.5 m apart and facing each other, play identical sounds of the same frequency. you stand halfway between them, where there is a maximum of sound intensity. moving from this point toward one of the speakers, you encounter a minimum of sound intensity when you have moved 0.33 m . assume the speed of sound is 340 m/s.part a) what is the frequency of the sound? part b) if the frequency is then increased while you remain 0.21 m from the center, what is the first frequency for which that location will be a maximum of sound intensity? express your answer to two significant figures and include the appropriate units.
