Question

An object that has negative acceleration is definitely doing what?

speeding up

maintaining a constant speed

slowing down(incorrect)

accelerating in a direction that is opposite to a stated positive direction.

Answer 1

it is accelerating in a direction that is opposite to a stated positive direction

Step-by-step explanation:

it's going backwards if positive is up then negative is down in ur case it's the opposite direction of forward

Answer 2

An object with 0 acceleration is accelerating in a direction that is opposite to a stated positive direction.

Step-by-step explanation:

Acceleration is not always based on speeding up or slowing down (a constant speed is no acceleration at all), it's also based on direction. If you state that an object is positively accelerating when you throw it upwards, then it's negatively accelerating when it's falling even though it's velocity is increasing.
