Two pieces of clay are moving directly toward each other. when they collide, they stick together and move as one piece. one piece has a mass of 300 grams and is moving to the right at a speed of 1 m/s. the other piece has mass 600 grams and is moving to the left at a speed of 0.75 m/s. what fraction of the total initial kinetic energy is lost during the collision?

Laboratory experiments, observational field studies, and model-building are all examples of different forms of scientific investigations.  in what way do laboratory experiments primarily differ from other forms of scientific investigations?   a.  a laboratory experiment is the only accepted form of investigation within the scientific community.  b.  studies about how things behave in nature or studies involving very large objects are best answered through laboratory experiments.  c.  laboratory experiments involve the identification and control of variables.  d.  data can only be generated through laboratory experiments, not other forms of investigation.
