Answer:
Centripetal acceleration is related to tangential velocity through ac = v ^ 2 / R
The angular velocity is related to the tangential velocity through ω = v / R
a) ac = (20 m / s) ^ 2/20 m = 20 m / s ^ 2
b) ω = 20 m / s / 20m = 1 rad / s
c) The swept angle is Ф = ω.t = 1 rad / s. 3600 s = 3600 rad
Expressed in turns it is Ф = 3600 rad. 1 turn / (2.π rad) = 573 turn
