12. On her way to visit her Grandmother, Ked Kiding Hood sat down to vest and Place her 1.20- kg basket of goodies beside her. A wolf came along, spotted the basket and began to pull on the handle with a force of c. 40N at an angle of 250 with respect to vertical. Ked was not going to let go easily , so she pulled on the handle with a force of 12. cow. if the net force on the basket is straight up , at what angle Was Red Riding Hood pulling from the Vertical ? 13. A person is doing leg lifts with 300 kq ankle weights . The lower leg itself has a mass of 51. 00 kg. When the leg is held still at an angle of 30 .0 ' with respect to the horizontal , the patellar tendon pulls on the tibia with a force of 342 N at an angle of 20. 0' with respect to the lower leg. Assume the force exerted on the tibia by the femur is the only other significant force acting on the lower leg . Find the magnitude of the force exerted on the tibia by the femur
