A 2410 kg car traveling to the west at 22.6 m/s slows down uniformly.

How long would it take the car to come to a stop if the force on the car is 8880 N to the east? Answer in units of s

What is the car's displacement during the time it takes to stop? Answer in m

2. Relevant equations

d = .5at^2 + Vit

3. The attempt at a solution

2410 * 22.6 = 54466 kg*m/s (the momentum)

8880 N is also 8880 kg*m/s^2

54466 / 8880 = 6.133558559 seconds (this is right)

d = .5at^2 + Vit

d = (.5)(22.6/6.13355)(6.13355^2) + (22.6*6.13355)

d = 207.9273 m

I got the time, but when i plug in the displacement it's wrong
