1. A bee flits from flower to flower. If it leaves the hive and travels 210 m [N32*E] and then 37 m [S51'W], how far and in what direction is the bee from its hive? 2. A 100-N force is applied to the end of a 50-cm wrench and makes an angle of 45* with the handle of the wrench. a) What is the torque on a bolt at the other end of the wrench? b) What is the maximum torque that can be exerted by a 100-N force on this wrench and how can it be achieved? 3. Determine the area of a triangle with vertices A(2, -1, 4), B(3, 1, -1), and C(1, 0, 2). 4. Given the points A(1, 2), B(5, 4), find the angle AOB where O is origin of cartesian system
