Consider the initial velocity of the balls is u. Initial kinetic energy can be expressed, This kinetic energy is independent of direction. As the balls hit the ground the final velocity becomes zero. Apply law of energy conservation, From above expression it is clear that initial velocity only depend on height not on direction. Thus, vA = vB = vCCorrect order:vA = vB = vC

George walks to a friend’s house. He walks 750 meters North, then realizes he walked too far. He turns around and walks 250 meters South. The entire walk takes him 13 seconds. What is his velocity in meters per second? Also, is the acceleration due to gravity negative or positive or it depends? I'm really confused. Please help and explain in an easy to understand.
