Solve the given problem:
Problem: A person driving her car at 51.0 km/hr approaches an intersection just as the traffic light turns yellow. She knows the yellow light lasts only 1.70 s before turning to red, and she is a distance D=35.0 m away from the near side of the intersection. If she decides to stop, how far from the intersection will she come to a stop? The intersection is W=10.0 m wide. Her car's maximum decelleration is -6.30 m/s2.
A- The car can accelerate from 51.0 km/hr to 74.0 km/hr in 6.30 seconds. How far from the intersection will she be when the light turns red?
