Q1. A person walks 21° north of east for 3.30km. How far would another person walk due north and due east to arrive at the identical location?

Q2. A small 0.528 kg object moves on a frictionless horizontal table in a circular path of radius 1.3 m. The angular speed is 6.18 rad/s. The object is attached to a string of negligible mass that passes through a small hole in the table at the center of the circle. Someone under the table begins to pull the string downward to make the circle smaller. If string will tolerate a tension of no more than 105N, what is the radius of the smallest possible circle on which the object can move?
