sorry the uphill component is only for the box, the box is moving to the right towards the hill and the wind is moving horizontal in the same direction as the box.
Well.. I guess that would make sense. I just feel like the question needs more information. But lets say we use you idea why would omega in a) be 0 if we are going to check it just after it is released?
in a) I have to find omega just after it is released would it still be zero then?
and in c) if it would be released in that state why would it not be zero?
