3. A bored shuttle astronaut swings a 3.0 kg Crescent wrench around in a circle of radius R = 1.5 m on the end of a tether with constant speed. Each revolution of the wrench takes 0.75 seconds. A) Find the tension in the tether. B) Find the work done by the tension on the wrench in one complete revolution. Sketch the wrench at an instant and think about θ. What is cos θ? Alternatively, think about the displacement for a complete circle.
