    Work and Center of Mass
    A 0.5kg weight has a string of negligible mass attached to it. You grab the other end of the of the string and swing your arm, giving the weight a speed of 4m/s and lifting its center of mass by 1.2m. What is the work done by the tension in the string onto the weight?
