While moving in, a new homeowner is pushing a box across the floor at a constant velocity. the coefficient of kinetic friction between the box and the floor is 0.43. the pushing force is directed downward at an angle θ below the horizontal. when θ is greater than a certain value, it is not possible to move the box, no matter how large the pushing force is. find that value of θ.

(b) what is the maximum value of the inducted electric field at a point 5.85 cm perpendicular from the axis of the solenoid?

22. the top of a cliff is located a distance h above the ground. at a distance h/2 there is a branch that juts out from the side of the cliff, and on this branch a bird's nest is located. two children throw stones at the nest with the same initial speed, one stone straight downward from the top of the cliff and the other stone straight upward from the ground. in the absence of air resistance, which stone hits the nest in the least amount of time?
