(14 points) A 10 kg Teflon object on a level surface has a coefficient of static friction and kinetic friction of 0.04 with the surface. (Interestingly, Teflon has approximately the same static and kinetic coefficient of friction which is quite uncommon.) This Teflon box has a rotating thruster which rotates in the vertical plane normal to the surface that exerts a thrust of 15 N. If the thruster starts pointing upward (thrusting the box toward the surface) and starts rotating to the horizontal position, at what angle will it rotate before the box begins to move
