Bruce stands on a bank beside a pond, grasps the end A) A small mass is swung in a circle at constant speed using of an L = 20.0m long rope attached to a nearby tree and swings a string. The total work done by the tension is zero for one out over the water. If the rope starts at an angle of 40.0 with revolution. The vertical, what is Bruces speed at the bottom of the swing? B) The kinetic energy can be negative. C) The kinetic energy of an object does not depend on the direction of the motion involved. D) Work cannot be done in the absence of motion. E) If the earth revolves around the sun in a perfectly circular orbit, then the sun does not do any work on the earth. F) The work done to raise a box onto a platform does not depend on how fast it is raised.
