**A student in a physics class made a picture of this.**

A stoplight 20 m to the west turns yellow. Your car is traveling west at 12 m/s. You hit the brakes and decelerate at a rate of 6.0 m/s2. Your car stops before it reaches the stoplight (which is considered to be at the origin). A student in a physics class made a picture of this. x to = 0 s xo = + 20 m vo = – 12 m/s a = – 6.0 m/s2 Which of the following is labeled wrong? Did the student mislabel anything? 1 xo 2 vo 3 a 4 a & vo 5 all of the values are correct

**What are the signs of the three missing variables?**

A stoplight 20 m to the west turns yellow. Your car is traveling west at 12 m/s. You hit the brakes and decelerate at a rate of 6.0 m/s2.
