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.
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...
