Question

Hi I need help to figure out if these situations are possible or impossible thank you.

constant velocity, non-zero net force

constant speed, non-zero net force

velocity to the left, net force to the right

decreasing velocity, increasing magnitude of net force

Answer 1

if the net force is not zero, then there is a resultant acceleration, increasing velocity.

Answer 2

ok so that means numbers 1 and 2 would be impossible, and I got for 4 that it could be possible if the object is getting heavier to pull. But for 3 I'm not sure. Thanks
