a car is traveling at a constant speed of Vo on a straight, level road. After the brakes are applied at t=0 seconds, the motion can be approximated by: x=t^3/100-t^2 +17t where x is the distance traveled in meters and t is the time in seconds. Determine: A the initial velocity (Vo), B. the time required for the car to stop, C. The distance required for the car to stop, and D. The maximum deceleration during braking.
