Two identical twins hold on to a rope, one at each end, on a smooth, frictionless ice surface. They skate in a circle about the center of the rope (the center of mass of the two body system) and perpendicular to the Ice. The mass of each twin is 81.0 kg. The rope of negligible mass is 2.5 m long and they move at a speed of 5.90 m/s. center of mass (a) What is the magnitude, in kg. m/s,...

Two skaters, each of mass 40 kg, approach each other along parallel paths separated by 4.0 m. They have opposite velocities of 2.1 m/s each. One skater carries one endof a long pole with negligible mass, and the second skater grabs the other end of it as she passes. The skaters then rotate around the center of the pole. Assume thatthe friction between skates and ice is negligible.(a) What is the radius of the circle they now skate in?2 meters(b)...

Constants Part A Two identical twins, Jena and Jackie, are playing one December on a large merry-go-round (a disk mounted parallel to the ground on a vertical axle through its center) in their school playground in northern Minnesota. Each twin has a mass of 30.1 kg. The icy coating on the merry-go-round surface makes it frictionless. The merry-go-round revolves at a constant rate as the twins ride on it. Jena, sitting a distance 1.76 m from the center of the...

Two ice skaters hold hands and rotate, making one revolution in 2.90 s. Their masses are 57.0 kg and 72.0 kg, and they are separated by 1.30 m. Find the angular momentum of the system about their center of mass. Answer in kg m^2/s. If the skaters pull towards each other and decrease their separation to 0.80 m, what is the new period of rotation about the center of mass?
