A student at another university repeats the experiment you did in lab. Her target ball is 0.860 m above the floor when it is in the target holder and the steel ball she uses has a mass of 0.0120 kg. She finds that the target ball travels a distance of 1.45 m after it is struck. Assume g = 9.80 m/s^2. What is the kinetic energy (in joules) of the target ball just after it is struck?
