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 2.10 m/s2 or travel faster than 10.3 m/s , what is the minimum time in which an elevator can travel the 373 m from the ground floor to the observatory floor

The value is

Explanation:

From the question we are told that

The maximum acceleration is

The maximum velocity is

The height of the observatory floor is

Generally at the initial state of the motion the elevator accelerates from rest with a maximum acceleration to attain a maximum velocity at a time period of

Then it continues with the maximum velocity for a time period of

and finally decelerates with a maximum deceleration to come to rest at a time period of

Generally the velocity of the elevator for the first part of the motion is

given that it started from rest u = 0 m/s

=>

=>

Generally from kinematic equations the distance covered during the first part of the motion is

=>

=>

Generally the distance covered during the second part of the elevators motion is mathematically represented as

Generally given that the first part of the elevator motion is similar to the third part of the elevator motion it implies that the distance covered is similar

i.e

The total distance covered is mathematically repented as

=>

=>

Generally the minimum total time taken is

Generally

So

=>

i would think it's food chain

ill do it for 100, also this isnt 80 its 40
