# Question: A certain elevator cab has a total run of 190

A certain elevator cab has a total run of 190 m and a maximum speed of 305 m/min, and it accelerates from rest and then back to rest at l.22m/s2.

(a) How far does the cab move while accelerating to full speed from rest?

(b) How long does it take to make the nonstop 190 m run, starting and ending at rest?
