physics: BOB or DRWLS follow up question

What average force is required to stop an 1100-kg car in 8.0 s if it is traveling at 95 km/h?
i understand what you both did, but why can't you use the V = Vo + at equation and solve for acceleration there and use that in the EF = ma equation?
Sure. a= averageforce/m
Then solve for average force. Same equation.
