A car comes to a stop for a stop sign in 4.6 seconds. If it was initially traveling at 27.5 m/s, how much space did it take for the car to stop?

physics 
bobpursley,
Vf=Vi+at solve for a.
then
Vf^2=Vi^2 + 2ad solve for d. 
physics 
Steve,
what is Vi?

physics 
bobpursley,
vi=27.5m/s

physics 
Steve,
this is where get stuck
vf=27.5(a)(4.6)
vf=126.5
i don't know the rest 
physics 
Steve,
please help me im realy stuck
