Solve the all parts of given question:
Question: A ball is launched from ground level with a particular launch angle, measured from the horizontal. The launch speed is 20.0 m/s. The ball reaches a particular maximum height. It continues to follow a parabolic trajectory until it lands at the same level from which it was launched, thus achieving a particular range and a particular time of flight. Note that air resistance can be neglected in this problem. If the ball is fired again from the same place, with the same launch angle, but with the launch speed doubled to 40.0 m/s.
Part A: Find the time of flight increases by a factor of _____?
Part B: Find the ball's maximum height increases by a factor of _____?
Part C: Find the range increases by a factor of _____?
