(I'm sorry if this is a bad way to frame a math question)
Let's say a car is moving at 40m/s and a brake is applied, the car decelerates at 10m/s thus stops after 4 seconds, traveled 100m after the brake is applied.
Now a different car is moving at unknown speed, a brake with different deceleration is applied and the car stops after 8 seconds, but also traveled 100m.
Is it possible to find out what is the initial speed AND the deceleration of the second car?
I have been trying to find if there's a formula to this, but i can only find either the formula include time or distance, but not both.
