Since. we need the acceleration in m/s square
Find the circumference of the circle first...
use m as a unit instead of cm
That turns out to be Π/4m.
Π is pi...
in one second, it covers twice the circumference i.e. Π/2 m.
so its velocity is Π/2 m/s.
now centripetal acceleration is given as v square/r
a= Π sq./2 or an approx of 4.81 m/s...
