Answer:
7.4 m/[tex]s^{2}[/tex].
Step-by-step explanation:
When an object rotates around a fixed center in a circular path of radius R then centripetal force acts on the object ,
Centripetal acceleration equals
[tex]\frac{v^{2} }{r}[/tex] Where,
v is the velocity of the object rotating in circular motion
and r is the radius of the circle.
Here , r = 65 meters.
v = 22 m/s.
Thus centripetal acceleration equals [tex]\frac{22^{2} }{65}[/tex]
= 7.44 m/[tex]s^{2}[/tex].
Thus option A is the best option i.e., 7.4 m/[tex]s^{2}[/tex].
