1. The problem statement, all variables and given/known data A certain elevator cab has a total run of 197 m and a maximum speed is 307 m/min, and it accelerates from rest and then back to rest at 1.21 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 197 m run, starting and ending at rest? 2. Relevant equations i thought you could use v=vo + at and v= d/t 3. The attempt at a solution what i did was first convert 307 m/min to 5.12 m/s then i said 5.12 = 0 + 1.21 (t) then t= 4.23 seconds so then i said v= d/t and 5.12= d/4.23, so d= 21.66 m then i did part b and said 5.12= 197 m/t and t= 38.48 s both of my answers were wrong please help?
