A constant 10-N force acts on an object.  The object starts from rest at x=0 and moves as shown in this animation.  The vector represents the net force on the object.

If at t=2 s, you apply an additional force of 10-N to the left, describe the motion of the object after you apply this force? (View answer)

If at t=2 s, you apply an additional force of 15-N to the left, describe the motion of the object after you apply this force? (View answer)

If at t=2 s, you apply an additional force of 5-N to the right, describe the motion of the object after you apply this force? (View answer)

If at t=2 s, you apply an additional force of 5-N to the left, describe the motion of the object after you apply this force? (View answer)

Suppose you apply a force at t=2 s and you want to stop the object.  What force do you have to apply?  Your Answer:  Apply a force of N for s, and then apply a force of . (Note:  there is more than one possible answer.  Can you find more than one possible answer?)

Suppose you apply a force at t=2 s and you want to stop the object exactly at t=6 s.  What force do you have to apply?  Your Answer:  Apply a force of N for s, and then apply a force of .
