You and your little brother are rolling toy cars back and forth to each other across the floor. He is sitting at x = 0, and you are at x = 4.0 m. You roll a car toward him, giving it an initial speed of 2.2 m/s . It stops just as it reaches him in 3.0 s.
In what direction is the car's acceleration?
A. The acceleration is in the +x direction.
B. The acceleration is in the −x direction.
I picked B but it was wrong. Can anybody explain it to me?
What is the car's average acceleration?
*My attempted answer: -0.28 m/s^2
