An object moving along a straight line is initially moving at a velocity of +12 m/s, but is accelerating so that at a time 4 sec later it is moving at the same speed, but in the opposite direction. What is the object’s average acceleration during the 4 seconds?
What is -6 m/s2?
200
a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position
What is displacement?
200
Distance traveled/ time of travel
What is speed?

A cart that is free to move in one dimension is moving in the positive direction and slowing down under the influence of a constant backwards pull until the cart comes to a momentary stop and reverses direction. What are the signs (negative or positive) of the cart’s velocity and acceleration during the moment it is stopped.
What is velocity: 0; accelerations: -?
