On a beautiful winter Sunday, you drag your two nieces in a sleigh on a snowy sidewalk. You pull on the rope with a force of 50N oriented 30 degrees above the horizontal. Julie, 25 kg, is in the first sled. Behind her, tied by another rope, is Marie's sled, 15 kg. Calculate the acceleration experienced by your nieces:  Calculate the tension in the middle string (between the two sleds):
