The diagram shows a gymnast (65 kg) performing a backward giant swing followed by a dismount. The numbered figures are in chronological order. In position 1, the gymnast has no angular velocity.

 

Considering only positions 1 to 4, in which position(s), and for what reason(s), does the gymnast possess the greatest clockwise angular acceleration?

Select one:

a. Position 4 because this is only image showing a clockwise torque acting on the gymnast

b. None of these positions because gravity is only producing counter-clockwise torques on the gymnast

c. Position 3 because the gymnast is moving the fastest clockwise

d. Position 4 because the moment arm from the bar to the gymnast's center of mass is the longest

e. Position 2 because it has the longest moment arm where the weight of the gymnast would be tending to rotate the gymnast

f. None of the positions because the gymnast is never rotating in the clockwise direction

g. None of the other answers are correct
