Q. Suppose the traffic light is hung so that the tensions T1 and T2 are both equal to 84.7 N. Find the new angles they make regarding the x axis. (By symmetry, these angles would be the same.)

Q. A box of books weighing 350 N moves with a constant velocity across the floor when it is pushed with a force of 439 N exerted downward at an angle of 30.7 degrees below horizontal. Find out mu k between the box and the floor.
