The driver of a car going 90.0 km/h suddenly sees the lights of a barrier 35.0 m ahead. It takes the driver 0.75 s to apply the brakes, and the average acceleration during braking is -10.0 m/s2.
(b) What is the maximum speed at which the car could be moving and not hit the barrier 35.0 m ahead? Assume that the acceleration doesn't change.
