Two ice skaters are gliding together along the ice, both moving at a constant velocity (sliding without exerting a force). The first skater (the one in the back), with mass M1 = 59 kg, pushes the second skater (the one in front), with mass M2 = 70 kg, directly forward in the direction they are initially moving. After the push the first skater is not moving (velocity = 0) and the second skater is moving with a velocity of 1.35 m/s.What is the initial speed of the skaters? Give your answer in m/s to three significant digits.
