# M1 question watch

1. I have worked out that resistance force is 575n for a but for b, why doesn't he resistance stay the same even though the object is not on a hill anymore? In b the answer involves using 575n but how could it work? Thank you.

the resistance in this problem is non gravitational

What do you mean by non gravitational in this question?? Thanks

air resistance for example

Yes I understand that there is only one resistance force which is 575 worked out in a. But what I don't understand is that since the object is not on the hill, one of the horizontal force will be removed, so surely resistance will be bigger as a result?but the answer uses 575 , which I don't get Thanks

still the same air resistance

still the same air resistance
It doesn't make sense though, I would never have thought of that in the exam...

makes perfect physical sense
The air resistance should not change
