A car traveling at a speed of 24 m/s comes to a stop at a red light.How much time will it take for the car to stop if its acceleration is –8.0 m/s2?

Use the equation final velocity = initial velocity + acceleration × time. Since the car stops, its final velocity is 0 m/s: 0 = 24 m/s + (−8.0 m/s²)t. Solving gives t = 24 ÷ 8.0 = 3 s, so the correct choice is 3 s.
