Elisha Graves Otis invented the elevator brake in the mid- , making it possible to build tall skyscrapers with fast elevators. Today’s skyscrapers are a large fraction of a mile tall; for example. Taipei in Taiwan has stories and is ( miles) tall. The top speed of the elevator in the Taipei tower is roughly three times greater than the ascent rate of a commercial jet airplane. The position and time data in the table are based on such an elevator.

a. Working in SI units, make a position-versus-time graph for the elevator.

b. Describe the motion of the elevator in words.

c. Find the highest speed of the elevator. When is the elevator going at this speed?

d. What sort of considerations would the engineers need to make to ensure the comfort of the passengers?

An unstretched ideal spring hangs vertically from a fixed support. A 0.4 kg object is then attached to the lower end of the spring. The object is pulled down to a distance of 0.35 m below the unstretched position 0.20 and released from rest at time t-0. A graph of the subsequent vertical position y of the lower end of the spring as a function of t is given above, where y=0 when the spring was initially unstretched.

1) At which time is the upward velocity of the object the greatest? (A) 0.00 s (B) 0.25 s (C) 0.50 s (D) 0.75 s (E) 1.00 s 

2) What is the spring constant of the spring? (A) 16 N/m (B) 20 N/m (C) 32 N/m (D) 40 N/m (E) 64 N/m
