A disk rotates about its central axis starting from rest and accelerates with constant angular acceleration. At one time it is rotating at 10.0 rev/s. After 60 more complete revolutions, its angular speed is 15.035 rev/s ... Calculate the angular acceleration

1.05 rev / (s) 2

Explanation:

Here the disc is travelling from constant angular acceleration there for we can use motion equation for angular acceleration

(V) 2 = (U) 2 + 2aS

V - final angular velocity

U - initial angular velocity

S - revolution

a - angular acceleration

(15.035) 2 = (10) 2 + 2 * a * 60

a = 1.05 rev / (s) 2
