Maybe the answer you are getting for part 1 is not positive...

Homework Statement A helicopter is flying in a straight line over a level field at a constant speed of 6.8 m/s and at a constant altitude of 9.9 m. A package is ejected horizontally from the helicopter with an initial velocity of 11.0 m/s relative to the helicopter, and in a direction...

Ugh! Yes you're right, and I used kinetic, not static, for part 1... But I still am curious as to why my result of 31.7 deg is wrong. I was hoping someone could spot something wrong with my equation to part 2.

To solve for part 1 I used Ffriction = us*N I don't see anywhere in my work where I had static friction = coeff. of kinetic * N Sorry if I was misleading with my post - I updated it after someone pointed out I had forgot the actual problem I was having.

I am embarrassed... I just updated my original post with the trouble I am having.

I know equations. For part two the question is referring to static friction because the mop is at rest.

Homework Statement In the figure a fastidious worker pushes directly along the handle of a mop with a force F. (Note: For picture, imagine a worker standing in the second quadrant pushing the mop head into the origin) The handle is at an angle θ = 23.58° with the vertical, and 0.30 and 0.22...
