Final answer:
When velocity is negative and acceleration is positive, the object will be slowing down.
Step-by-step explanation:
When velocity is negative and acceleration is positive, the object will be slowing down. Although acceleration is in the direction of the change in velocity, it is not always in the direction of motion. In this case, the object is moving in the negative direction (opposite to the positive direction) and the positive acceleration is acting to slow it down.
