On her way to visit Grandmother, Red Riding Hood sat down to rest and placed her 1.7-kg basket of goodies beside her. A wolf came along, spotted the basket, and began to pull on the handle with a force of 6.0 N at an angle of 28° with respect to vertical. Red was not going to let go easily, so she pulled on the handle with a force of 17 N. If the net force on the basket is straight up, at what angle was Red Riding Hood pulling?
