Your friend's 11.1g tassel hangs on a string from his rear-view mirror. When he accelerates from a stop light, the tassel deflects backward toward the rear of the car. If the tassel hangs at an angle of 6.89deg relative to the vertical, what is the acceleration of the car?

Like poles repel, unlike attract. The term North pole, or South pole, is a very misleading and confusing term, to be avoided. Check your text on that. Most use the term N-pole, or S-pole, which means North seeking pole, or South seeking pole. Those are much more meaningful terms.
