Testable Question: How well does each basketball player perform after drinking water, Gatorade, or Powerade? Hypothesis: If a player drinks water to stay hydrated during a game, then that player will perform better than the players who drank Gatorade or Powerade because water is a natural resource and will keep the body hydrated best. Control Group: players not drinking water, Gatorade or Powerade to stay hydrated. Experimental Group: players drinking water, Gatorade, or Powerade to stay hydrated. Independent Variable: water, Gatorade, and Powerade. Dependent Variable: how well the players preform. Constant: the amount of liquid each player consumes during the game (such as one-half liter every quarter).
Without friction, Newton's second law, in the form F=ma would apply.100=50a. So the acceleration should be 2m/s^2100-friction = 50x1.5100-friction = 75100-75=friction25N = friction
