• A) Its speed will be greatest just after it is released.
• B) Its acceleration is zero just after it is released.
• C) As it moves farther and farther from Q, its acceleration will keep increasing.
• D) As it moves farther and farther from Q, its speed will decrease.
• E) As it moves farther and farther from Q, its speed will keep increasing.
