Answer:
0.556 m, yes
Explanation:
Objects moving in a circle experience a centripetal acceleration (ac) towards the center of the path. This acceleration is equal to the square of the speed (v) divided by the radius (r) of the path.
ac = v² / r
968 m/s² = (23.4 m)²/ r
r = 0.566 m
This is a realistic arm length for a human being.
