Let me get this straight:

the car, STARTING at vi

vf=vi+at

10=vi+50a

and

distance=vi*t+1/2 a t^2

200=50vi+1/2 a (2500)

two equations, two unknowns. From the first, Vi=10-50a, put that into the second,

200=50(10-50a)+ 1250a

200=500-2500a+1250a

-300=-1250a

a= 3/12.5 m/s^2 and vi=10-50a, so you have vi, a.

Now figure distance in 60 seconds
