1) Two people, George who has a mass of 85.0 kg and Victoria who has a mass of 62.0 kg, are on a frozen circular pond. They stand at the very centre and push off of each other. The distance from one side of the pond to the other is 83.0 m and it takes George 11.0 s to reach the edge of the pond. How long does it take Victoria to reach the edge of the pond?
