both of theoretical mass 50 kg, are ice skating and approach each other along parallel paths separated by 3.0 m. We have opposite velocities of 1.4 m/sec each. Will carries one end of a long pole of negligible mass and I grab the other end as I pass. Assume that the friction between skates and ice is negligible. What are (a) the radius of the circle? (b) our angular speed? And (c) the kinetic energy of our two-skater system? Next, we pull along the pole until we are separated by 1.0 m. What are (d) our angular speed and (e) kinetic energy of the system? (f) What provided the energy for our increased kinetic energy?

Along the line connecting the two charges, at what distance from the charge q1 is the total electric field from the two charges zero? express your answer in terms of some or all of the variables s, q1, q2 and k =14ï€ïµ0. if your answer is difficult to enter, consider simplifying it, as it can be made relatively simple with some work.
