decreasing.

The speed of the object is increasing

Explanation:

From the definition of force;

F = ma 1

Where m= mass

a = acceleration

Where acceleration is the rate at which speed/velocity increases. When a force act in the same direction as the motion of an object, then the object accelerate (i.e velocity increases) no matter how small the force is. As the force reduces the rate of increase in speed/velocity reduces but the object speed still increases at a lower rate. When the force is totally removed then the object will move at constant speed.

nah.   i'm just sleepy.

the answer is b, have negligible mass
