The graph shows the upward speed of a ball thrown up with an initial speed of 27.0 m/s from the surface of Jupiter. Select ALL correct answers in alphabetical order, i.e.. B. AC. BCD... The ball's PE is a constant. The acceleration is 0 near t=1.2s. Maximum height is reached at about t=1.2s. The ball's KE increases during the first second. The velocity vector and the acceleration vector are in the same direction after t=1.2s. The acceleration is constant.
