Answer: A) positive
Positive acceleration speeds the object up. Negative acceleration, aka deceleration, slows the object down. Zero acceleration means the object either keeps the same speed or isn't moving at all (we can say the speed is 0).
When an object speeds up, the positive acceleration occurs.
What is acceleration?
The acceleration is the time rate of change of velocity.
a = dv /dt
If the velocity is increased, the acceleration also increases, time remains same to cover a fixed distance.
Speeding up the object means positive acceleration. Negative acceleration also called deceleration slows the speed. Zero acceleration represents that the object is moving with constant velocity.
Thus, the positive acceleration occurs.
