Question
A 1550 kg car is traveling with a speed of 12.4 m/s. What is the magnitude of the horizontal net force that is required to bring the car to a halt in a distance of 50.3 m?
I found the force of the car to be 14700 by using F=ma. I am confused on what to do with the rest of the problem. Please help! Thank you

the distance traveled is
s = 12.4t - a/2 t^2 = 50.3
The velocity is
v = 12.4 - at = 0
Solve that and you get a = 4.59
Now you can use F=ma
s = 12.4t - a/2 t^2 = 50.3
The velocity is
v = 12.4 - at = 0
Solve that and you get a = 4.59
Now you can use F=ma
