An object moving in the direction 120 degrees (as measured counterclockwise to the positive x axis) encounters a net force whose direction is 270 degrees.
Sketch the force and its component along the line of motion, as well as its component perpendicular to the line of motion.

Suppose you are facing in the direction of motion. Do you perceive the component of the force along the line of motion to be forward or backward? It this component
in the direction of motion or opposite to the direction of motion?
answer/question/discussion: ->->->->->->->->->->->-> : It would be forward, I think. You said I'm facing the direction of motion, so I would think this means the motion and force is in front of

I'm not sure you understand the orientations being described here.
You are facing the 120 degree direction.
The force is exerted at 270 degrees.
This might or might not affect your answer.

Will the object speed up, slow down or maintain a constant speed?
answer/question/discussion: ->->->->->->->->->->->-> : Not sure I understand. If the object moving at 120 degrees encounters the object at 270 degrees, then if it's going in the same direction,
it would collide and possible speed up the 120 object, if they are both going in the same direcion. Although, if wouldn't have as much effect if the force is not

You don't want to assume a second object or a collision. There is a net force, which would be regarded as continuous, on the object.

coming at the same angle from behind, (angles are not equilibriants of each other).
#$&*
If you are facing in the direction of motion, then the line perpendicular to the direction of motion will run to your right and to your left. Is the component of the
force perpendicular to the line of motion directed to the right or to the left?
answer/question/discussion: ->->->->->->->->->->->-> : I don't understand the question. The 2 forces described don't seem perpendicular to each other.
#$&*
Will the object veer to the right, to the left or maintain straight-line motion?
answer/question/discussion: ->->->->->->->->->->->-> : If the forces were perpendicular wouldn't something like 45 and 135 degrees?
@&
45 and 135 degrees are perpendicular directions.
But these directions have nothing to do with the directions given in the problem.

#$&*
Which is greater in magnitude, the component of the force along the line of motion or the component perpendicular to the line of motion?

I'm not sure you've read the problem as intended. Please check my notes and submit another attempt.
