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?

Estimate the kinetic energy of mars with respect to the sun as the sum of two terms, that due to its daily rotation about its axis, and that due to its yearly revolution about the sun. (assume mars is a uniform sphere with mass = 6.4Γ10 to the power of 23 kg, radius = 3.4Γ10 to the power of 6 m, rotation period = 24.7 hours, orbital period = 686 days and is 2.3Γ10 to the power of 8 km from the sun.)
