Plsss when forces are unbalanced on an object, the object could: (choose all that apply) : travel at a constant velocity. decelerate. stop moving. remain at the same speed. start moving. accelerate. remain stationary.

As we know from the Newton's II law we can say

here if force is unbalanced then it is for sure that net force on the system is non zero

so here the object must have some acceleration here

so here we can say that object must have change in velocity due to unbalanced force present on it

now the correct option in this case must satisfy the change in velocity condition.

SO correct answers will be

Decelerate.  

Stop moving.  

Start moving.  

Accelerate.
