friction: k=1.6

mass of car m=750kg

power of engine w=350kw

g=9.8

distance x=500m

After a corner, the car comes out at velocity=31.9m/s

There is a 500m straight next but have to finish it at 31.9m/s for next corner.

I need to know the fastest way to complete the 500m.

how can i work out the maximum velocity i can go and when to start braking?

i think we found the braking eqaution was a=-gk but we are basically really stuck!

any help would be greatly appreciated!

thanks
