"Two identical balls are thrown directly upward, ball A at speed v and ballB at speed 2v, and they feel no air resistance. Which statement about these balls is correct?" O Ball B will go twice as high as ball A because had twice the initial speed. O Ball B will go four times as high as ball A because it had four times the initial kinetic energy. O The balls will reach the same height because they have the same mass and the same acceleration. O "At its highest point, ball B will have twice as much gravitational potential energy as ball A because it started out moving twice as fast"
