Two ice skaters are gliding together along the ice, both moving at the same, constant velocity (sliding without exerting a force). The first skater (the one in the back), with mass M1 = 62.3 kg, pushes the second skater (the one in front), with mass M2 = 70.4 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 3.70 m/s.
What is the initial speed of the skaters? Give your answer in m/s to three significant digits. You will not be graded on the number of significant digits, this is just to be sure your answer is not counted incorrect due to rounding.
Do not include units in your answer.
(Note: You can assume the friction of the ice on the skaters can be neglected.)

Part III: Solve the following problems Two skaters gliding on ice run into each other head-on. If the two skaters hold onto each other and continue to move as a unit after the collision, what will be their resultant velocity? Skater A has a velocity of 5 m/s and a mass of 65 kg. Skater B has a velocity of 6 m/s and a mass of 60 kg.

need help with this two questions, please !!
Two ice skaters, Daniel (mass 60.0 kg) and Rebecca (mass 45.0 kg), are practicing. Daniel stops to tie his shoelace and, while at rest, is struck by Rebecca, who is moving at 13.0 m/s before she collides with him. After the collision, Rebecca has a velocity of magnitude 7.00 m/s at an angle of 54.1" from her initial direction. Both skaters move on the frictionless, horizontal surface of the rink. What is...
