•At what point in time (seconds) does the car turn around?

• A

• B

• C

• D

• E

•What is happening B-C?

• the car is at rest

• the car is moving at a constant speed backward

• the car is moving at a constant speed forward

• the car is accelerating forward

•What is happeningA-B?

• the car is at rest

• the car is moving at a constant speed backward

• positive

• negative

• it's impossible to tell

• positive

• negative

• it's impossible to tell
