A certain elevator cab has a total run of 192 m and a maximum speed is 315 m/min, and it accelerates from rest and then back to rest at 1.10 m/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 192 m run, starting and ending at rest?
