Problem
A projectile is launched vertically upward. An energy bar chart shows that at launch the kinetic-energy bar is 6 units tall and the gravitational potential-energy bar is 0 units tall. Neglect air resistance. When the projectile is at half of its maximum height, the potential-energy bar is 3 units tall. What is the height, in units, of the kinetic-energy bar at this instant?
