I WILL MARK YOU AS BRAINLIEST IF RIGHT A 1125 kg car was traveling at 20 m/s toward a traffic signal when the light suddenly turned red. The driver stomped on her accelerator, clearing the intersection in 1.7 seconds and coming to a speed of 24.6 m/s . What was the acceleration of the car?

An object's kinetic energy is proportional to its speed squared, which means doubling a car's speed quadruples its energy. A car going 100 mph therefore has more than twice as much kinetic energy as a car going 70. Similarly, in the time it takes the slower car to stop, the faster car won't have even slowed to 70 mph.
