Identical twins Kate and Karen are rowing their boat on a hot Summer afternoon when they decide to go for
a swim. Kate, whose mass is 53 kilograms, jumps off the front of the boat at a speed of 3.00 m/sec. Karen
jumps off the back at a speed of 4.00 m/sec. If the 70-kilogram rowboat is moving at 1.00m/s when the girls
jump, what is the speed of the rowboat after the girls jump?
