1. The problem statement, all variables and given/known data A Physics textbook weighing 3 kg needs must be launched into a nearby trash can. The velocity necessary to accomplish this feat is 4 meters per second when unleashed in its flight. Assume no wind resistance. What energy is necessary to accomplish this deed? 2. Relevant equations Kinetic energy = .5 * mass * velocity^2 3. The attempt at a solution .5 * 3 kg * 16 m^2 s^-2 = 24 Joules Kosher? Thoughts?
