1kWw 3 kg J 77777 1981B2 A massless spring is between a 1 kilogram mass and a 3 kilogram mass as shown above but is not attached to either mass Both masses are on a horizontal frictionless table In an experiment the 1 kilogram mass is held in place and the spring is compressed by pushing on the 3 kilogram mass The 3 kilogram mass is then released and moves off with a speed of 10 meters per second Determine the minimum work needed to compress the spring in this experiment
