A 50 g ball is thrown from a window with an initial velocity of 8.0 m/s at an angle of 30# above the horizontal. Using energy methods, determine (a) the kinetic energy of the ball at the top of its flight and (b) its speed when it is 3.0 m below the window. Does the answer to (b) depend on either (c) the mass of the ball or (d) the initial angle?

Chapter 3 Key Terms of Bioenergetics Energy – capacity to do work Work – application of force over distance – Force * distance = work Power = work / time – Work done quickly as fast as possible Metabolism – total amount of energy expended Anaerobic Metabolism – without oxygen Aerobic Metabolism – oxygen must be present for...
