Question

If angular velocity of a disc depends an angle rotated theta as = theta 1 - 2 theta . then its angular acceleration at alpha
theta=1 rad is :
(A) 8 rad/s2
(B) 10rads2
(C) 12 radis
(D) None of these​

Answer 1

Answer:

a=de/dtheta

theta1 -2 theta will become zero while derivation

so none of the above

Answer 2

C. 12 radis
