throw a ball vertically upward. When you let go of the ball, it has a kinetic energy K0 (assume the ball has zero gravitational potential energy at the point where you let go). Without air drag, the ball reaches a maximum height h above the point where you let go. You throw the ball again, this time giving it a kinetic energy of 3*K0. What will be the maximum height of the ball (again without air drag)? (Note that the square root of 3 is approximately 1.73)
