2. Batman (60 kg) and Superman (100 kg) are standing at opposite ends of a 30 m log (40 kg) that is floating in calm water. (Batman is on the left.) (a) Draw a figure of the situation, including all relevant given informa- tion. (b) Find the coordinate of the center of mass for this system, assuming Batman is at the origin. (c) Batman and Superman both walk away from their original loca- tions. Superman walks a distance of 25 m on the log, while Batman walks a distance of 10 m on the log. What are the new coordinates for Batman, Superman and the log, as measured from Batman's original location? (Hint: I did not give you any of the answers to this question. You have to figure them all out yourself with the information given.) (d) If each person spends 5 seconds walking to their new location, what are Batman's, Superman's and the log's velocities during that time?
