A car is traveling at 72 km/hr. The driver begins to apply the brakes and the begins to slow with a constant acceleration (a). After the brakes are applied, the car stops in a distance of 100 m. What is the acceleration?

My teacher gave the class a list of formulas but didn't really go over them with some examples. I still wondering on what formula to use.

1 answer

A car is traveling in the +x direction. The driver applies the brakes and slows down. The acceleration is in the —— direction. -x, -y, +z, +x, 0
