A car travelling at the speed Vo on a straight level road. After the brakes are applied at t = 0, the motion can be approximated by s = t^3/100− t^2 + 17t where s is thedistance traveled in meters and t is the time in seconds. a. gives the value of Vo b. gives the distance required for the car to stop.
